If it can be screwed up, I'll find a way :) 

But clearly this can happen because that is precisely
what does happen when TRE is being linked. Some symbols
are coming from TRE and some from the C library.

BTW: Felix will enforce linking the right library automatically.
But my example wasn't using the technology that does that yet,
I was just trying to check my C++ version of tre worked.

Funny thing is .. if this is supposed to be a replacement
for GNU regex .. well it obviously cannot support dynamically
switching the libraries around. The functions are compile time
compatible but not link time compatible: the compiled regexp
object of TRE is obviously smaller than the GNU one, and 
the GNU regcomp was clobbering memory.
