Bug while using GMP 4.2.2

I've had several problem using your lib with the program attached to this mail.
First of all i had segmentation fault if i didn't reinitialize the
value of d1, d2 or d3 before every use (comment line 134 for example).
And then after trying many examples on this software i found that
sometimes there were errors. And here is what i discovered: the value
of the variable name tmpm is changed btw the line 133 and 135 even if
i don't use this variable btw those 2 lines.

I've compiled the lib using ABI=32 and --disable-alloca and also
recompiled with just ABI=32 and had the same problems.

output of gcc -v:
