--- Comment #7 from Misty De Meo <misty at brew dot sh> --- Checking the GCC database, I noticed a similar issue regarding GCC 4.4.3: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47609 Checking the symbol list in libgcc_s and libstdc++, I can see that it's true that OS X 10.4's GCC C++ stdlib doesn't include that symbol; the OS only shipped with GCC 4.0.1. I assume GCC 4.4's libgcc_s/libstdc++ includes it, so perhaps the problem is that the GCC 4.8 build is pulling in the wrong library. Unfortunately I don't have the machine available for testing until next week.
