I realise these issues are difficult to diagnose, however, if you can't 
reproduce it, what chance does anyone else have?  All the regex exceptions 
are thrown from void regex_error::raise() in regex.cpp BTW, so you could set 
a breakpoint in there and then run under the debugger - multiple times if 
necessary - until it gets trapped.  Otherwise do please try and boil it down 
to a test case: quite often that process can itself lead to the 
identification of the bug.
