The last gmp upload failed to build on hurd-i386 and kfreebsd-i386 and I could use some help. The code builds but seven test cases segfault [1]. Can someone help debug these and hopefully provide a patch?
It crashes also for me inside kvm. The key point seems be advertised CPU, not architecture. The patch bellow suffices for me to pass whole testsuite. --- mpn/x86/p6/mmx/gmp-mparam.h +++ mpn/x86/p6/mmx/gmp-mparam.h @@ -53,7 +53,7 @@ #define MUL_TOOM42_TO_TOOM63_THRESHOLD 80 #define SQR_BASECASE_THRESHOLD 0 /* always (native) */ -#define SQR_TOOM2_THRESHOLD 48 +#define SQR_TOOM2_THRESHOLD 30 #define SQR_TOOM3_THRESHOLD 81 #define SQR_TOOM4_THRESHOLD 142 #define SQR_TOOM6_THRESHOLD 258 The upstream should read their own comments in source code ;-) A few lines before that is: /* NOTE: In a fat binary build SQR_TOOM2_THRESHOLD here cannot be more than the value in mpn/x86/p6/gmp-mparam.h.
