Maybe its about gcc 4.1 on SuSE.
I wrote this:

GCC 4.1,
GCC 4.2: There is a known incompatibility between Python and GCC,
         where GCC 4.1 and later uses an interpretation of C 
         different to earlier GCC releases in an area where the C 
         specification has undefined behaviour (namely, integer 
arithmetic 
         involving -sys.maxint-1).

         As a consequence, compiling Python with GCC 4.1/4.2 is not
         recommended. It is likely that this problem will be resolved
         in future Python releases. As a work-around, it seems that
         adding -fwrapv to the compiler options restores the earlier
         GCC behaviour.

so what should i do now??
