It seems likely to me that one of your thirdparty libs contians a
    CriticalSection symbol.

I think you may be able to discern this from a map file. Read the docs
    on how to make your linker generate a map file. If gnu ld is your
    linker, I believe -Wl,-M will do the trick.

Please read:
http://gcc.gnu.org/onlinedocs/gcc-3.2.2/gcc/Link-Options.html#Link%20Options
    and scroll to the bottom of the page.

Please read:
http://sources.redhat.com/binutils/docs-2.12/ld.info/Options.html
    and search for '--print-map' .

I think so, but I think a thirdparty lib is more likely the culprit.
