While compiler bugs are always a possibility, C has "unspecified" so many
parts of its behavior, that many bugs in your programs can stay hidden until
some compiler's optimization bumps into them.
So it's actually more probable that it's a bug in our code, which happens to
be uncovered by one of the -O2 optimizations.
