I'm using gimp and gegl's GIT version. Both versions from 2017/12/26 work just fine.

But with Gegl GIT (2017/12/28) and the unchanged Gimp (2017/12/26) I get a crash while just scrolling an image in Gimp.

It doesn't crash for me - and thus far no reports on IRC in #gimp.

The backtrace gives:

Can anybody reproduce this? If not, what can I do to help locating the bug?

I'm using gcc-7.2.0.

Figuring out which particular commit of the commits making changes to gegl/buffer/gegl-buffer-access introduces the crash would be helpful, it shouldn't even need a git bisect - and you can do the make && sudo make install from within the gegl subdir in GEGL to avoid also having to rebuild all operations. On my system it doesn't crash, which image precision (bitdepth) is it crashing for, and using what cpu/distro/kernel?

Hi,
Segmentation fault in gegl_buffer_iterate_read_simple

[...]

This should be fixed now in GEGL master, by commit 03bdb529bccfcc5bc51dd02bc266d901a4af6300 (see also bug 792018).
