Title:
qemu crashes on Darwin in qemu_iohandler_poll
Status in QEMU:
New
Bug description:
I have an issue when I try to run qemu-system-arm on Mac OS X.
Sometime between 1 and 15 secs after qemu is started it crashes
as shown bellow.
Same thing on linux host works fine.
Is anybody else experiencing this?
Any Hints?
Thanks,
Damjan
