Speaking from general point of view, it would be nice to compile the failing
program (regcomp) and its shared libraries with debug information.  However I
don't have any advice on how to actually do it in this build environment.

>From the backtrace and some googling it seems like the problem could be - and it's
just a wild guess - because of exceptions.  In particular I've seen something like
this when libgcc_s.so used at run-time came from a compiler different than a
compiler which was used to produce an executable.  In my case it was libgcc_s.so
from base gcc at run-time versus libgcc_s.so from gcc45 at link-time.  My program
crashed on any 'throw' statement (even when an exception should have been caught).
 Again, I am not saying that this is what happens here, I am just hinting at
things to try.

P.S.  I have not debugged the actual mechanics of the crash that I have described
