tarball of GLSL source code for use in Fragmentarium
I'm using $ apt-cache policy libgl1-mesa-dri

I will try to compile upstream Mesa soon to see if it is a Debian-specific
issue, or whether it has already been fixed in a later version.
Fragmentarium (from https://=
github.com/3Dickulus/FragM ) crashes inside
radeonsi_dri.so when I try to compile part of a large shader project (~50kB=
of
GLSL transcluded from the main 'raymond/example.frag'). The problematic pa=
rt
is the last half of 'raymond/Raymond-Trace.frag' in the attached tarball,
setting #if 0 stops it from crashing and emits an error message in the shad=
er
compile log about missing function definitions (this is expected, the hard
crash with #if 1 is not).
It seems to be caused by something that passes a nullptr as a field name in
compiler/glsl/ir.cpp:1401, gdb backtrace is large:
Thread 1 "Fragmentarium-2" received signal SIGSEGV, Segmentation =
fault.
