Very basic bug

[Álvaro Begué]

GMP version: 4.2.1


Sample program:

#include <iostream>
#include <gmpxx.h>

int main(){
  mpz_class a=1,b=1,c=0;
  a=c+b*a;
  std::cout << a << std::endl; //Should print 1, but prints 0
}


The only configuration option I used when building the library was --enable-cxx


Output of `gcc -v':

Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v
--enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr

x86_64-linux-gnu
Thread model: posix
gcc version 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)


Output of `uname -a':

Linux downstairs 2.6.17-10-generic #2 SMP Fri Oct 13 15:34:39 UTC 2006
x86_64 GNU/Linux


`./config.guess' and `./configfsf.guess' both output:

x86_64-unknown-linux-gnu


I compiled it with:

g++ bug.cpp -o bug -O6 -lgmpxx -lgmp -static


Let me know if you need anything else.

Thanks,
Álvaro.
