Subject: remove incorrect fflush from assert failure handler
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=47baa0301ffc18e62239588a521440dede3adb7e;p=musl

remove incorrect fflush from assert failure handler

assert is not specified to flush open stdio streams, and doing so can
block indefinitely waiting for a lock already held or an output
operation to a file that can't accept more output until an
unsatisfiable condition is met.
