Yes, very likely. MacPorts does not pass any -march or -mtune arguments by default to the compiler. The gmp port even disables archive_sites to force a build on the local machine. The Portfile points to ticket in Trac [1], which is inaccessible at the moment. The crash log tells us it was an illegal instruction: Exception Type: EXC_BAD_INSTRUCTION (SIGILL) Exception Codes: 0x0000000000000001, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY The instruction can be found at this location: Thread 8 Crashed: 0 libgmp.10.dylib 0x000000010005bfa9 __gmpn_sqr_basecase + 9 In the libgmp.10.dylib I built locally, there is no suspicious instruction at this location: $ otool -tv /opt/local/lib/libgmp.10.dylib |grep -A6 ^___gmpn_sqr_basecase: ___gmpn_sqr_basecase: 0000000000025b40 cmpq $0x2, %rdx 0000000000025b44 jae 0x25b54 0000000000025b46 movq (%rsi), %rax 0000000000025b49 mulq %rax 0000000000025b4c movq %rax, (%rdi) 0000000000025b4f movq %rdx, 0x8(%rdi) Can you check this in the version you are shipping?
