[Qemu-devel] [Bug 1299858] Re: qemu all apps crash on OS X 10.6.8

[Peter Maydell]

My test system is OS X 10.8.5 built with clang "Apple LLVM version 5.0
(clang-500.2.79) (based on LLVM 3.3svn)", and QEMU works fine there,
which suggests a problem either with that version of GCC or that version
of MacOSX.

You might try building with clang rather than gcc; otherwise since I
don't have a system to reproduce on (or indeed much interest in tracking
down bugs in old versions of MacOS, to be honest) I'm afraid you'll have
to investigate this bug yourself if you want a fix for it.

Title:
  qemu all apps crash on OS X 10.6.8

Status in QEMU:
  New

Bug description:
  qemu-2.0.0-rc0 (and 1.7.1) crashes with SIGABORT in all apps when
  configured with --with-coroutine=sigaltstack (which is what configure
  selects by default) but all  run fine if configured with --with-
  coroutine=gthread.

  Crash is at line 253 (last line of Coroutine
  *qemu_coroutine_new(void)) in coroutine-sigaltstack.c in 2.0.0-rc0
  tarball.

  Platform is OS X 10.6.8 (Darwin Kernel Version 10.8.0), compiler gcc
  4.2.1

  Sorry for the sparse report but I'm short on time today.
