I believe that I have run into a binary compatibility issue on solaris/gcc-4.1.
A 12D build of 27.filebuf.codecvt works fine in 4.2.0, but if I use the 4.2.1 shared library I get 44418 failed assertions, and 1 fatal error which leads to an exit code of 9. I haven't had a chance to look into it yet, but I plan on doing so this afternoon. Travis
