I'll try to identify the function tomorrow.
That would be welcome. I looked through the function right now and saw
no obvious problematic candidate.
It's Simultaneous_music_iterator::pending_moment()
simultanous-music-iterator.cc is short enough to look through the
generated code manually. If you compile it (of course with all other
relevant options) and options -S (for generating assembly source) and
-fverbose-asm then I should have a reasonable chance of finding problems
in the generated code by manual inspection.
I moved everything but the problematic function to another file. I'm
attaching the files. simultaneous-music-iterator-O1.s is compiled
with -O1, simultaneous-music-iterator-O2.s is compiled with -O2.
That's x64_64 assembly. Please let me know if you want i386 assembly.
I'll try playing with the C++ code. That may give us a workaround for
Lilypond and a compact example for reporting to GCC developers.
