Segment fault at startup
Hi all,
megasync crashes at startup. I am running Fedora 34 on a Thinkpad X395.

cryptopp-8.6.0-1.fc34.x86_64 is currently installed. Megasync will start without a problem after downgrading to cryptopp-8.4.0-2.fc34.x86_64.
Thanks in advance.
Thanks for the report. The fix with the updated cryptoapp will be released soon.
Same here on a Thinkpad X1 running Fedora 34

Now there was an update (in reality a downgrade) from 4503.1 to 4503.0 which does not solve the problem.

Although I have been facing the same problem, I think this is a duplicate of #627 (although different Fedora versions are being mentioned, the problem is the same).

Facing the same issue. tried compiling from git repo but it doesn't compile (final execution of make), even though I followed the instructions.
Thorwing a bunch of errors (this is a list of only the error lines, not the full compiler ouput):

./control/MegaController.h:73:69: error: class ‘ProgressFuncExecuterListener’ does not have any field named ‘onRequestFinishCallback’

control/Utilities.h:230:47: error: ‘Q_NULLPTR’ was not declared in this scope
So unfortunately that doesn't work for now either.
downgrading cryptopp to version 8.4.0-2 fixes the error temporarily, as the OP described.
~~The new 4.5.3-3.1 version does not have the bug. However, it seems (at least in Fedora 34) that whenever I perform a dnf update, the new version gets replaced with the old (with the bug) version 4.5.3.0-1.~~
Nevermind, I got the version scheme wrong. 4.5.3-3.1 is the old version.
Through the brilliant advice from @polmr in Issue #627, this was fixed for me on Fedora 34 because of a "disagreement" between the mega packages—i.e., megasync and nautilus-megasync—in the MEGAsync and RPM Fusion repos.
By excluding megasync and nautilus-megasync in /etc/yum.repos.d/rpmfusion-nonfree-updates.repo, uninstalled the "tainted" packages, and reinstalling them from the MEGAsync repo, everything works as expected now.
