Walter, et. al.:

I'm compiling up the latest STLport because I'm getting some interesting and repeatable bugs in the 4.5.1 package as supplied (and there's something to be said for having the latest). In particular, the compiler issues the following warnings when expanding the std::List_node_base template:

dll_main.cpp(274) : Warning 12: variable 'std::_List_node_base _TMP169'
used before set
dll_main.cpp(274) : Warning 12: variable 'std::_Slist_node_base _TMP193'
used before set
dll_main.cpp(274) : Warning 12: variable 'std::_Slist_node_base _TMP193'
used before set

These symbols don't appear in the preproccessed output, so I'm left concluding that the error is a compiler issue. I'm using the latest and greatest 8.41.2n scppn.exe.

Sorry that the preprocessor output is so long. I'll try to shrink it down to size as time permits.

Command line would also probably help:

dmc -c -o"c:\tmp\dll_main.out" -Ae -Ar -DSTRICT -D__BUILDING_STLPORT -I../stlport -o+all -Nc -D_MT "dll_main.cpp"

Also, the bug doesn't reappear if -o+all is used, so it looks like there's a possible optimizer error.

I wouldn't worry about it. I investigated it once, and it turned out to actually be a use before set, but it was just used as a 'dummy'. So ignore the warning.

Ok. Apparently it's caused by the optimizer (-o+all). I'll see if I can narrow things down a little more, as in the specific option, if that would help. Because you know that newbies will repeatedly ask about this even if the side effects aren't harmful.
