I'm not personally worried about a fix for this, I reported it primarily
for the benefit of others/the quality of the codebase as a whole. As I
said, I got it working with gthreads as the coroutine provider so it's
working for my needs.
Although this seems on the surface to be a problem with the specific
platform versions involved it's always possible that this sheds light on
something that is either an undiscovered problem on more recent platform
versions or will become a problem.
It's notable that the version of xcode (and hence gcc) involved is the
last from Apple with PPC support. It's precisely why I'm using it and
it's precisely why someone who's targeting multiple platforms might be
using it and qemu in concert.
It's possible that a fix might be to get configure to select gthreads
support for OS X platforms below a certain compiler or OS version, or it
may be a deeper issue.

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.
