+qemu crashes on Darwin in qemu_iohandler_poll
+
+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

+I am seeing the same think when I try to run a sample built under gcc from the TI tools

+However Peter Maydell sent me a kernel image that runs fine on OS X.  However when I try to run it under gdb I get the same problem that you see.

+
+Can you still reproduce this issue with the latest version of QEMU, or could we close this ticket nowadays?
