Dear Maintainer, when comparing with a process while having debug symbols installed, I guess the given backtrace would translate to something like below.
Therefore I guess this crash is the same as described in #929113. Unfortunately I could not find a matching appearance of function gimp_projection_chunk_render_iteration. Additionally upstream has highly modified this file already. Therefore, if this is reproducable, running with installed debug symbol packages "gimp-dbgsym libglib2.0-0-dbgsym libgimp2.0-dbgsym" [1] and an attached gdb, issuing at the crash the commands 'info reg' and 'thread apply all bt full' could give some more insight. Kind regards, Bernhard Submitter: | Reconstructed: [0x7f05c7726e27] libgimpbase-2.0.so.0(gimp_stack_trace_print+0x397) | 0x00007fc6d8ca8e27 in gimp_stack_trace_print () from /lib/libgimpbase-2.0.so.0 [0x56063cab94a0] gimp-2.10(+0xd14a0) | 0x000055b3604154a0 in gimp_eek () at errors.c:377 [0x56063cab98d8] gimp-2.10(+0xd18d8) | 0x000055b3604158d8 in gimp_fatal_error () at errors.c:234 [0x56063caba037] gimp-2.10(+0xd2037) | 0x000055b360416037 in gimp_sigfatal_handler (sig_num=8) at signals.c:165 [0x7f05c6a2e730] libpthread.so.0(+0x12730) | <signal handler called> [0x56063ce2b97f] gimp-2.10(+0x44397f) | 0x000055b36078797f in gimp_projection_chunk_render_iteration () at gimpprojection.c:1416 [0x56063ce2bc28] gimp-2.10(+0x443c28) | 0x000055b360787c28 in gimp_projection_chunk_render_callback () at gimpprojection.c:857 [0x7f05c6c12dd8] libglib-2.0.so.0(g_main_context_dispatch+0x158) | 0x00007fc6d8194dd8 in g_main_dispatch () at ../../../glib/gmain.c:3182 [0x7f05c6c131c8] libglib-2.0.so.0(+0x4e1c8) | 0x00007fc6d81951c8 in g_main_context_iterate () at ../../../glib/gmain.c:3920 [0x7f05c6c134c2] libglib-2.0.so.0(g_main_loop_run+0xb2) | 0x00007fc6d81954c2 in g_main_loop_run () at ../../../glib/gmain.c:4116 [0x56063cab8cb7] gimp-2.10(app_run+0x357) | 0x000055b360414cb7 in app_run () at app.c:440 [0x56063cab85b5] gimp-2.10(main+0x395) | 0x000055b3604145b5 in main () at main.c:524 [0x7f05c687d09b] libc.so.6(__libc_start_main+0xeb) | 0x00007fc6d7dff09b in __libc_start_main () at ../csu/libc-start.c:308 [0x56063cab873a] gimp-2.10(_start+0x2a) | 0x000055b36041473a in _start () [1] https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols
