I'm getting a similar unhandled exception in the Intel Threaded Building Blocks library libtbb.so vex amd64->IR: unhandled instruction bytes: 0xF0 0x41 0xF 0xB0 ==19165== valgrind: Unrecognised instruction at address 0xD98690D. ==19165== Illegal opcode at address 0xD98690D ==19165== at 0xD98690D: tbb::internal::micro_queue::push(void const*, unsigne d long, tbb::internal::concurrent_queue_base&) (in lib/libtbb.so) ==19165== by 0xD986832: tbb::internal::concurrent_queue_base::internal_push(v oid const*) (in lib/libtbb.so) e909: b0 00 mov $0x0,%al e90b: b2 01 mov $0x1,%dl e90d: f0 41 0f b0 55 20 lock cmpxchg %dl,0x20(%r13) The easiest way to reproduce this is to download the Intel opensource TBB files and build, then run test_assembly.exe under valgrind http://osstbb.intel.com/ver.php?fid=72 download, extract the source and oss_lin binary libraries type make in the top level source directory Will make all the examples. running test program test_assembly.exe will hit the illegal instruction *** This bug has been confirmed by popular vote. *** Fixed (vex r1795). Will be in 3.3.0. Please verify. Verified. 3.3.0 works with TBB out of the box. valgrind crashes with the following version combination: valgrind-3.5.0 tbb30_056oss (linux_intel64_gcc_cc3.4.6_libc2.5_kernel2.6.18_release) Has this patch been maintained in valgrind 3.5.0? |
