   otool -tvV `which htop` > ~/htop.otool

Please include the generated file in your report.

Thank you for helping to improve htop!

zsh: illegal hardware instruction  htop

[BenBE]

Please include the output from otool as well as a few words on steps to reproduce (or at least what you were trying to do when the crash happened).

[svk77]

The crash happens as soon as I start the program. htop.otool.zip

[BenBE]

Okay, based on that information, the crash happens when its trying to put color/highlighting information into the text it's displaying:

https://github.com/htop-dev/htop/blob/4e6ec4a0873c56ca9de63eadf730c5bd677bd8da/Panel.c#L290

Can you have a look if there is a change when you do the following configuration changes (test one by one):

• Set highlight_deleted_exe=1 to highlight_deleted_exe=0
• Set find_comm_in_cmdline=1 to find_comm_in_cmdline=0
• Set strip_exe_from_cmdline=1 to strip_exe_from_cmdline=0

@fasterit: Can you try to reproduce on your system?

[svk77]

The program does not even create a config file. Empty along this path /Users/svk/.config/htop/ In /etc empty too

[svk77]

I'm trying to tell you that I can't change the configuration. Because the configuration file of this programm, on my system simply does not exist. Could the error be due to this? I didn't compile from source, I installed from brew.

Can I get a config file from you? In those files that are on the Internet, there are no these lines that I am offered to try to change.

[BenBE]

You can create a config file by taking the line below "Setting information" and replace ; by newline characters.

[svk77]

You can create a config file by taking the line below "Setting information" and replace ; by newline characters.

Ok, I tried to do so. And I tried to change the parameters as you recommended. However, nothing has changed. But now I see from the error log that the parameters are read by the application from the configuration file. But nothing has changed - still the same error. htoprc.zip

[fasterit]

@BenBE: I cannot reproduce this on a (real, hardware) Mac and macOS 11.7.1 20G918 x86_64. Note the zsh: illegal hardware instruction htop in the original bug report and the "hackintosh" this is running on.

[BenBE]

@fasterit thx.

@svk77 Can you give gdb (or any other debugger of your choosing) a shot and try to pinpoint exactly where things go south? The information of the process that is to be displayed when the process crashes would be good to know.

Also, you mentioned you were using the brew release version. Does this also happen if you compile the main branch from source yourself?

[ghost]

I got the same issue on a 15-inch MacBook Pro from 2017.

zsh: segmentation fault  htop

Installed using the Nix package manager.

I remember recently using Migration Assistant and transferred all the configuration files, so there might be configuration weirdness, but a well-behaved program shouldn't segfault because of that. In addition, my home directory is not my username.

htop.otool.gz

@chorismate You crash seems to have a different cause from the one in the first post. In your case the cause is caused by reading the battery information. To confirm this you can remove the Battery meter from your configuration (by editing htoprc manually. If you can find your way around gdb or another debugger, please take a look at the value of power_type returned around line 500 in Platform_getBattery.

      CFStringRef power_type = CFDictionaryGetValue(power_source, CFSTR(kIOPSTransportTypeKey)); // <-- That return value here

      if (kCFCompareEqualTo != CFStringCompare(power_type, CFSTR(kIOPSInternalType), 0)) // Crash happens here inside CFStringCompare
         continue;

[BenBE]

@svk77 I did a small fixup in the rendering code that might resolve your issue. Would be nice if you could test commit b810678 (from the main branch) and checking if this resolves the issue. If the issue persists, please check in a debugger, what the contents of the local variable item were when the crash occurs.

[ghost]

@BenBE Yes, it fixes the issue. (Thanks!)

I'm not clear on how to use a debugger though; I don't have a lot of time to look into it.

I got same problem as @latticecrystalline, installed via Nix on MacOS (12.6.9), Macbook 2015, x86. Tried to run the built but got error on not loaded libncursesw. Will try tomorrow again. Looks like setting LD_LIBRARY_PATH not works?
