Bug ID: 376870 Summary: The impossible happened on Mavericks 10.9 Product: valgrind Version: 3.12.0 Platform: Other OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: memcheck Assignee: jsew...@acm.org Reporter: hamish-...@risingsoftware.com Target Milestone: --- I am trying to run my app in memcheck on Mavericks/10.9. (It is actually running in a 10.9 virtual machine in Parallels 11, because the host is running Sierra/10.12 which is not supported yet.) I got quite a few messages about an unhandled syscall: --10283-- WARNING: unhandled amd64-darwin syscall: unix:446 --10283-- You may be able to write your own handler. --10283-- Read the file README_MISSING_SYSCALL_OR_IOCTL. --10283-- Nevertheless we consider this a bug. Please report --10283-- it at http://valgrind.org/support/bug_reports.html. At the point when I expected my program to crash, I got: eq_SyscallStatus: {78 0 43} {78 0 40} valgrind: m_syswrap/syswrap-main.c:438 (Bool eq_SyscallStatus(UInt, SyscallStatus *, SyscallStatus *)): the 'impossible' happened. host stacktrace: ==10283== at 0x238042521: ??? ==10283== by 0x238042932: ??? ==10283== by 0x238042915: ??? ==10283== by 0x2380C13FE: ??? ==10283== by 0x2380C0989: ??? ==10283== by 0x2380BEDDB: ??? ==10283== by 0x2380BCCCD: ??? ==10283== by 0x2380CE1CC: ??? sched status: running_tid=1 and a stack trace. -- You are receiving this mail because: You are watching all bug changes.
