Same on Raspberry Pi Zero and Raspberry Pi Zero W.

[Pulikutti]

Same on Pi Zero W. reverted to 2018.6.2

Program received signal SIGSEGV, Segmentation fault. 0x00060ea0 in runtime.moduledataverify1 (datap=0x36333b31) at /usr/local/go/src/runtime/symtab.go:517

[xyzulu]

Exactly the same issue as well. It's also being reported elsewhere. Reverting to 2018.7.2 works..

the issue is 2018.7.3

[ghost]

@xyzulu how do you revert to 2018.7.2? I can't find the binaries for download.

[xyzulu]

Here: https://bin.equinox.io/a/4SUTAEmvqzB/cloudflared-2018.7.2-linux-arm.tar.gz

[angussidney]

I have also reproduced this issue on my Raspberry Pi Model 1B (rev 2). Reverting to 2018.7.2 as xyzulu suggested works.

[rix1337]

Same issue, same device

[cvocvo]

+1 for same issue on a RPi Model B; 2018-7.2 works but I keep randomly running into this (https://github.com/cloudflare/cloudflared/issues/23) same error with 2018-7.2. failed to connect to an HTTPS backend and then have to reboot the Pi.

Would love to get this fixed to try a later version of Cloudflared that hopefully resolves that problem :)

[dullroar]

+1 on all of the above, including falling back to 2018-7.2 works.

[tconnz]

Same issue here on RPi B - Segmentation Fault.

EDIT- 2018-7.2 only works if copied to usr/local/bin and then chmod +x is run.

[CBielstein]

Same issue with a Raspberry Pi model A. Falling back to 2018-7.2 worked without any further steps.

[silvether]

+1 Can repro on Raspberry Pi 1 B+ with Raspbian Minimal

[jmvermeulen]

Same here on Pi 2.

[Chlorus]

+1 for a Raspberry Pi 1 Model B+, haven't tried reverting to an older version yet.

[double-fault]

Falling back to 2018-7.2 does work on a Raspberry Pi Zero W.

[joehillen]

I ended up building from source on my Pi Zero W, and it works like a charm. Had to add an extra swapfile in order for the build process to have enough RAM.

I suspect cloudflare's ARM build instance is to blame.

[ravvle]

I also had this issue on the Pi Zero W, building from source fixed this for me. I had to add extra swap space to compile properly. Thanks @joehillen

Note: I compiled using Go 1.11.5. I noticed the build config seems to use the 1.9 stream which doesn't receive patches any more.

[dsadsa897897r]

What command is needed to compile using Go?

sudo apt-get install golang
export GOPATH=$HOME/go
go install github.com/cloudflare/cloudflared/cmd/cloudflared

[sssilver]

Hi,

The next cloudflared release will be built with Go 1.11.

[hexdra]

Same error on Pi B Version 2019.2.1. 2018.7.2 works.

[ArniDagur]

@sssilver Since there has been a new release, does that mean this issue is fixed?

[timothybrown]

@sssilver Since there has been a new release, does that mean this issue is fixed?

Does not appear to have been fixed. I tried the current release today and it’s still segfaulting.

cloudflared version 2019.4.1 (built 2019-04-19-2152 UTC) (official binary download)) Works on Raspberry Pi 3b+

[cleanev]

Same issue on RPiZeroW with latest Rasberry Pi Stretch with all updates and name showing - Linux ZeroPiHole-I 4.19.42+ #1219 Tue May 14 21:16:38 BST 2019 armv6l GNU/Linux

Latest version 2019.4.1 only works with RPi3B+

Name resolution with 2018.7.2 does not work at all

I referenced this article when setting up DoH - https://docs.pi-hole.net/guides/dns-over-https/

[billthefarmer]

I think the segfault issue is due to released cloudflared being built on a later ARM processor, or cross compiled. The latest current version (2019.5.0) works fine on a Pi 3 B+, whether it stops working after a while (#23), I don't know, didn't test it for long enough, but segfault on a Pi 1B (BCM2835). I installed go1.12.5 linux/arm on the Pi 1B and built from source, release 2019.5.0 plus a few commits (babcd9f), this appears to work, but stops working after a while (#23), it appears to run out of file handles.

Update: Having looked at the Makefile, I built version 2019.5.0 using it...

This version may be ok, it's now been running for several hours including a Pi reboot and a router reboot.

[billthefarmer]

Version 2019.5.0 built with go1.12.5 on a Pi 1B as in previous post eventually failed due to running out of file handles after about a week...

Just checking in that the issue continues with version 2019.6.0

[billthefarmer]

The latest version from https://bin.equinox.io/c/VdrWdbjqyF/cloudflared-stable-linux-arm.tgz gives an instant segfault on a Pi 1B. I can't tell the version because it won't run.

pi@jennifer:~/cd $ tar xzvf cloudflared-stable-linux-arm.tgz

Update: Version 2019.6.0 builds and runs OK on a PI 1B using go1.12.5 linux/arm, downloading an amazing long list of stuff from various sources.

Somewhere I found a tgz file that was compiled for 32 bit Pi, I am assuming those are zero, zero w, a and some older ones? Upon checking the version I have is 2019.5.0 that works perfectly fine on ZeroW. Can’t seem to find the original post or url that hosted the file, however I do have a copy that I can share. I am not sure how to attach it here. Let me know if someone has a website where I can upload

[billthefarmer]

I have on soak test on a Pi 1B an old version I got from here: https://web.archive.org/web/20180419005946/https://bin.equinox.io/c/VdrWdbjqyF/cloudflared-stable-linux-arm.tgz, linked from here: https://web.archive.org/web/20180524132333/https://developers.cloudflare.com/argo-tunnel/downloads, which is version 2018.4.6. It's third choice, so it may take a while to fail if it's going to.

A recent version built from source using a recent Go compiler seems to fail after a while as above.
