Conflicting symbols from oniguruma and libc cause segfault / bad memory writes about mruby-onig-regexp

Hmm, what can we do...

Looking at both struct definitions, it looks like what onigposix.h is trying to do is to (very unsafe-ly) wrap around the posix regex implementation. The "real" oniguruma regex implementation seems to be defined in "oniguruma.h". I don't really understand much about regular expressions or oniguruma, but is there a reason that you used the onigposix.h API and not the native oniguruma.h API? Did you use MRI as sample code? Maybe they have an answer.

I solved it (I think)! All I had to do is add -lonig to the linker flags of my application (that statically links mruby), and indeed in your binding, the CPU jumps into libonig instead of libc and there are no more crashes.
