Since an upgrade to Fedora 21, I get crashes with QEMU when using
-daemonize. I noticed this since libvirt could not QMP probe QEMU.
This is the command line used:
x86_64-softmmu/qemu-system-x86_64 -S -no-user-config -nodefaults
-nographic -M none -pidfile /tmp/foo -daemonize
Here's the backtrace from the coredump:

I am using today's tip of the QEMU git tree, but I don't think that's
the actual problem.
Anyone have an idea? I reinstalled glibc, but that doesn't seem to solve
what looks like a mutex problem.
