+Subject: [PATCH] dwflpp::function_entrypc avoid usage of uninitialized memory
+
+Failure on 3.3 release was observed. Failure was elusive and
+disappeared after seemingly random configure option change, or when
+code was compiled with -O1 or -O0 (vs default -O2). Running failing
+test case under valgrind memcheck pointed to couple places where
+'Conditional jump or move depends on uninitialised value(s)' occured.
+
+After addressing these in two places in dwflpp::function_entrypc,
+valgrind memcheck run is clean and original issue got fixed.
+
+Upstream-Status: Backport
