-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
