My first thought is that this may either be an alignment issue given
that the versions of gcc are different between 3.1 & 4.0, library
differences, or both.  Different alignment, different arguments, a
different argument order, or simply fewer or more arguments would all
result in the misinterpretation of a return address.  An incorrect
return address would send execution into the weeds.

If you see the same behavior after (re)compiling everything with 4.0's
gcc, I would consider this as being ominous.
