It is not safe to make such assumptions.
There was a code generation bug in egcs-1.0.3 that was often triggered
by the inline pow function from glibc. This was a bug in the compiler,
not a bug in the asm. It was fixed for egcs-1.1.
Just because two bugs may seem to have certain characteristics in common
does not mean they are the same problem. You have to actually debug
the problem to be sure.
