Title:
qemu on ARM hosts aborts on startup because makecontext() always fails
Status in QEMU:
Fix Committed
Status in Linaro QEMU:
Fix Released
Bug description:
qemu has recently grown a coroutines implementation. There are two
versions, one using the makecontext/setcontext/swapcontext functions
from ucontext.h, and one falling back to implementing coroutines as
separate glib threads. configure chooses the former if the platform
has a makecontext().
Unfortunately ARM eglibc provides a makecontext() which always fails
ENOSYS, which means the configure check passes but when qemu starts it
abort()s.
The best fix for this is probably going to involve making the
coroutine implementation runtime-selectable.
