Gimp crashes at startup

By activating OpenCL in GIMP, I get

Thread 1 "gimp" received signal SIGSEGV, Segmentation fault.
0x00007fffd3416227 in ?? () from /usr/lib/libigc.so.2

All ok if OpenCL is disabled.

Maybe Gimp should be rebuilded? Or GEGL? Or is it a GIMP bug?

Re: Gimp crashes at startup

Do you have a better backtrace that isn't just the last stack position and ideally using https://wiki.archlinux.org/title/Debuginfod ?

Now that you know the licence for the package, you'll surely understand how to fix the crash, right?

Re: Gimp crashes at startup

The line he was looking (and I also somewhat asking) for was

gc: 81 file totali, 0 file alterati

Please avoid bloating the thread with full quotes of previous posts and then

Do you have a better backtrace that isn't just the last stack position and ideally using https://wiki.archlinux.org/title/Debuginfod ?

Re: Gimp crashes at startup

If I unset GEGL_USE_OPENCL=gpu, Gimp starts.
Then, it seems a bug in GEGL with the new intel opencl drivers.

Re: Gimp crashes at startup

Yup.
The backtrace is gonna be much longer than that, can you post the rest of it?

gdb only gives this after downloading the symbols.

Re: Gimp crashes at startup

It uses a pager, have you tried to move up/down w/ the arrow or page keys?

I'm stupid, but not that stupid.

Re: Gimp crashes at startup

You're looking at the stored coredump there?
And that's the *entire* output when you enter

thread apply all backtrace full

into gdb???

No, that's what comes out after `run` in gdb. But I'm not at my computer right now, so I'll post the entire coredump tomorrow when I get back to my PC.

I doubt Arch can do anything about it, though, as it's probably an upstream issue.

Re: Gimp crashes at startup

The longer trace should make it easier (also for the upstream devs)  to spot the cause or an existing bug.
