4Subject: [PATCH] dwflpp::function_entrypc avoid usage of uninitialized memory
5
6Failure on 3.3 release was observed. Failure was elusive and
7disappeared after seemingly random configure option change, or when
8code was compiled with -O1 or -O0 (vs default -O2). Running failing
9test case under valgrind memcheck pointed to couple places where
10'Conditional jump or move depends on uninitialised value(s)' occured.
11
12After addressing these in two places in dwflpp::function_entrypc,
13valgrind memcheck run is clean and original issue got fixed.
