MacOS 10.6, valgrind-svn from a couple weeks ago. vex x86->IR: unhandled instruction bytes: 0x66 0xF 0xBF 0x44 ==880== valgrind: Unrecognised instruction at address 0x307dab. ... ==880== Process terminating with default action of signal 4 (SIGILL) ==880== Illegal opcode at address 0x307DAB ==880== at 0x307DAB: frexp$fenv_access_off (in /usr/lib/libSystem.B.dylib) Actual instruction: 0x97c42dab <frexp$fenv_access_off+107>: movsww 0x8(%esp),%ax I see lots of SIGILL bugs in the bugbase but none for this function/instruction. Should I log a new bug? |
