This happened on Linux as well somewhere. I looked at this, and it
seemed that A called B called C, B and C are static, B gets inlined
into A, C gets inlined into B. Any change to gcc's inlining algorithm
(like changing the size of the function) caused the crash to go away.
I couldn't come up with a small test case.
IIRC you can get around this by compiling without optimization, or
perhaps even -fno-inline
