Subject: Initialize variable in py_get_event_thread
X-Git-Tag: users/ARM/embedded-binutils-master-2018q4~995
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bbbbbceebc342d583057a11d88bae85f451cd904;p=thirdparty%2Fbinutils-gdb.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.
