From 5f9bf810441d37a1ab3626a67c9369ea27243915 Mon Sep 17 00:00:00 2001 From: Jia Tan Date: Wed, 28 Jun 2023 20:31:11 +0800 Subject: [PATCH] liblzma: Prevent uninitialzed warning in mt stream encoder. This change only impacts the compiler warning since it was impossible for the wait_abs struct in stream_encode_mt() to be used before it was initialized since mythread_condtime_set() will always be called before mythread_cond_timedwait(). Since the mythread.h code is different between the POSIX and Windows versions, this warning was only present on Windows builds. Thanks to Arthur S for reporting the warning and providing an initial patch.
