Subject: Initialize variable in py_get_event_thread
X-Git-Tag: gdb-8.2-release~22
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c6f50f8869ac0dd10040f5c32387eb404f9ff50a;p=external%2Fbinutils.git

Initialize variable in py_get_event_thread

The pythread variable could be used without being initialized, fix it by
initializing it to nullptr.

gdb/ChangeLog:

	* python/py-threadevent.c (py_get_event_thread): Initialize
	pythread.
