32-bit Clang Release Builds failing ww8export Unit Tests

[Luke Benes]

It turns out this was a compiler bug that's also affecting FreeBSD. The LLVM developers are asking for help with a reproducer.  If you have any suggestions, the bug report is here:

I bisected the regression in clang and it turns out this was an optimization issue.  So it looks like there is a bug with '--enable-symbols' disabling optimizations, at least with clang.
