SIGSEGV in setAnchorPosition

[Olivier Croquette]

I have updated recently to 1.19.3 and I am experiencing since then random crashes. I was able to catch one in gdb. Here is the stack trace.

Thread 1 "ART.bin" received signal SIGSEGV, Segmentation fault.

Hi,

Is this from the linux64 binary, or did you build art yourself? If the latter, can you try with a debug build and give me more info about your environment?

[Olivier Croquette]

Hi, it is from the official linux64 binary. I can reproduce it now, it happens when I have started an interactive action with the cropping tool and I move to the next file with F4

[agriggio]

Thanks, I'll try to reproduce and go from there then!

[agriggio]

I didn’t manage to reproduce. Would you be able to create a short video that shows the steps you are taking? Thanks!

[Olivier Croquette]

I cannot reproduce it anymore either. Maybe there are prerequisites to trigger the crash. I will keep you updated if I find out more.

You can see the moment when I hit F4 in the windows title (title changes to next photo). ART hangs at that moment and takes a while to crash.

[agriggio]

prevent segfault when switching images while editing the crop

Fixes #292

Thanks, I managed to reproduce it now. I just pushed a patch that should fix this hopefully
