After running our program for more than a day there is a crash with SIGBUS. Here are the messages: ==01:02:38:32.373 2400== Warning: set address range perms: large range 268439552, a 1, v 1 ==01:02:50:00.615 2400== Warning: set address range perms: large range 268439552, a 0, v 0 --01:02:52:57.936 2400-- INTERNAL ERROR: Valgrind received a signal 7 (SIGBUS) - exiting --01:02:52:57.936 2400-- si_code=2; Faulting address: 0x4F4029EC; sp: 0x495A44610 valgrind: the 'impossible' happened: Killed by fatal signal ==01:02:52:57.936 2400== at 0x700C0FCD: disInstr_AMD64 (toIR.c:7954) ==01:02:52:57.936 2400== by 0x7008F238: bb_to_IR (bb_to_IR.c:187) ==01:02:52:57.936 2400== by 0x700688E5: LibVEX_Translate (vex_main.c:416) ==01:02:52:57.936 2400== by 0x7002354D: vgPlain_translate (libvex_basictypes.h:154) ==01:02:52:57.936 2400== by 0x70034759: handle_tt_miss (scheduler.c:596) ==01:02:52:57.936 2400== by 0x70034B81: vgPlain_scheduler (scheduler.c:717) ==01:02:52:57.936 2400== by 0x7004785E: thread_wrapper (syswrap-linux.c:86) ==01:02:52:57.936 2400== by 0x70047955: run_a_thread_NORETURN (syswrap-linux.c:119) ==01:02:52:57.936 2400== by 0x70047A86: vgModuleLocal_start_thread_NORETURN (syswrap-linux.c:206) ==01:02:52:57.936 2400== by 0x70050F2E: (within /usr/local/opt/x86_64-20050615/lib/valgrind/amd64-linux/memcheck) sched status: running_tid=3
SIGBUS on non-riscs is usually a sign of accessing an area mmap'd to a file, where the file is not long enough, and you are accessing off the end of the file. Can you re-run with --sanity-level=4 and see if it stops with a report of any kind of memory management problem? This will make V run more slowly but lets us find certain kinds of problems which might be the root cause of this.
Ok, after some days of runtime I got: --16041:0:aspacem Valgrind: FATAL: M_PROCMAP_BUF is too low. --16041:0:aspacem Increase it and rebuild. Exiting now. I try to increase the value.
Christoph, any further info on this one?
Yes, after increasing the value valgrind does not crash any more.
I'm closing crashing and similar bugs that are more than two years old. If you still see this problem with Valgrind 3.4.1 please reopen the bug report. Thanks.
