meson build with buildtype=release causes g-ir_scanner dies with SIGILL on AMD machine
GIMP version: 2.99
Operating System: Ubuntu 19.10
Package: self built, the problem is in the meson build.
Description of the bug
Building gimp with meson with buildtype=release seems to crash g-ir-scanner (?) and stop the build, whereas buildtype=debug does not.
Is the bug reproducible? Always
Command '['/home/gimp/_build/tmp-introspectnrkd9xnk/Gimp-3.0', '--introspect-dump=/home/gimp/_build/tmp-introspectnrkd9xnk/functions.txt,/home/gimp/_build/tmp-introspectnrkd9xnk/dump.xml']' died with <Signals.SIGILL: 4>.
Just preceding that was:
/usr/bin/g-ir-scanner -pthread -I/usr/include/gobject-introspection-1.0 .......
Expected result: build completes
Actual result: build stops
The workaround is: don't do that, use buildtype=debug. I know the meson build is experimental.
SIGILL is illegal instruction. Some tool is executing an illegal instruction?
gegl#190 (closed) seems pertinent. Possibly related to SMD instructions invoked when compiler is optimizing?
My hw is an older AMD Phenom.
I am building inside a vagga container, I haven't tested it outside the container.
