Oh well, that blows out my theory you might have been getting linked against
the wrong version of the libs (64-vs-32 bit) and hence get disagreements about
sizes of various integer types being passed on the stack as arguments.
Wait a minute! That stack trace shows 'this as having the same value in
frames 1, 2 and 3, it's 0x23f780 in all of them. That suggests that gdb is
parsing the stack right and the code is getting it wrong. I think you still
need to worry about sizes of stack arguments. Maybe there's a header file
somewhere that uses an int where it should have written long int, and nobody's
noticed until LP64 made them become different sizes?

Haven't tested this yet owing to wanting to keep my installation stable
while doing gcc testsuite runs. Should be able to give it a go tonight or
Can't think of a witty .sigline today....
