I have experienced tests/mpz/t-perfpow to fail when:
1/ building gmp-5.0.1 on 64bit MS Windows (Win7 if it does matter)
2/ using native 64bit gcc4 toolchain from (no
3/ the same results with gcc 4.4.4pre and gcc 4.4.3
4/ build from MSYS environment
5/ using configure options: --build=x86_64-w64-mingw32
--host=x86_64-w64-mingw32 --enable-static=yes --enable-shared=no
6/ t-perfpow is the only test that fails all other pass
7/ the same gmp-5.0.1 with the 32bit version of the same compilers (gcc
4.4.4pre and gcc 4.4.3) builds fine (all tests pass)

The failure details:

n = 973276029958642838685 .............
n was destroyed, but perfpow_p still believes n is a perfect power
Please contact the application's support team for more information.
FAIL: t-perfpow.exe

Thanks in advance for any suggestions.
