The unexpected values are returned by gmp_nextprime() and gmp_gcdext(). Both the values are produced by the corresponding MPIR functions. The problem is not in the gmp extension. These are behavior differences between MPIR and GMP. The next prime number (gmp_nextprime) from -1000 is expected to be 2, but could be -997 depending on the definition of prime numbers (can primes be negative?). A newer version of MPIR may fix this problem, however we can't upgrade to it due to license issues. This may get worked out eventually. For now, we've decided to fork the affected tests into Windows/MPIR specific tests. The attached patch fixes this issue. Actual result: -------------- 003+ string(4) "-997" 003- string(1) "-2" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62068&edit=1
