Summary: Optimization flags cause warnings with STL list

Initial Comment:
When I place a std::list inside a struct and compile my code with -Os (or -O2) and warnings enabled I get the following warning:

stl_list.h:435: warning: '__p' might be used uninitialized in this function


Please see the attached full source code for an example.  Compile it with

"c:\MinGW\bin\g++.exe" -Os -Wall std-list_struct_bug.cpp


MinGW version used:  5.1.4
GCC version:  g++.exe (GCC) 3.4.5 (mingw-vista special r3)
OS:  Windows XP PRO SP2 64-BIT
Machine:  Dell Optiplex GX620 (3.2Ghz Pentium D)
