Hi, on a Pentium G4400, GMP 6.1.0 configured with --enable-fat crashes because of an illegal instruction:
Program received signal SIGILL, Illegal instruction.
0x00007ffff7501514 in __gmpn_submul_1_coreihwl ()
at tmp-coreihwl_submul_1.s:165
165 jmp .Llo3
(gdb) bt full
#0 0x00007ffff7501514 in __gmpn_submul_1_coreihwl ()
at tmp-coreihwl_submul_1.s:165
I can not reproduce it myself, it is a report from a different user.
http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/desktop-6th-gen-core-family-spec-update.pdf
says there is a bug in reporting BMI support. I am not sure how exactly
to read the document if the bug affects G4400 and if this is the real
reason of the crash.
Are you interested in working around hardware bugs?
Have a nice day,
Fero
