I am afraid I cannot say for sure what the problem might be.
This type of isolated, platform/tools specific failures are very rarely
GMP's fault. In few instances, GMP can reasonably work around these
type of problems. I can just give some general advice:
1. Make sure you're using the same version of gcc and g++ (and in
particular not gcc and a vendor C++ compiler, or vice versa.
2. Try another compiler version. (I have no particular prejudices
against gcc 4.3.3, which you say you're using, but I know gcc 4.3.2
was not able to correctly compile GMP 4.3.)
3. Isolate the problem. Start by running the test stand-alone and see
what error message you get. Then try to recompile things at the
lowest optimisation lever where the bug still happens, but add -g to
CFLAGS (i.e., do configure ABI=blahblah CFLAGS="-g -On ..."). First
and foremost avoid -fomit-frame-pointer, as it makes life hard for
Then, once you have a build with low optimisation and -g, fire up gdb
and follow the error backwards. Good luck!
