Details:

guile> (regexp-exec (make-regexp ".") (string #\nul))
throw from within critical section.
Abort trap
$ guile -v
Guile 1.8.1

If there is a null character anywhere in the string that any regular
expression is trying to match, then guile 1.8.1 throws something that is
impossible to catch, vis: 

guile> (catch #t (lambda () (regexp-exec (make-regexp ".") (string #\nul)))
(lambda (k . v) #t))
throw from within critical section.
Abort trap
$

This used to work in guile 1.3.4 but I haven't checked the versions in
between.  Please help?

Thanks, 
Grem
