Hey Stefan, You're right my regular expression was not escaped properly! I have put my code inside some try and catch braces, and everything works fine. BTW, I have had some problems with exceptions in gcc2.96 (not related to boost) linking dynamic libraries, but they seem to catch ok with the -fsjlj-exceptions compiler flag. Many thanks, Paul

Hi Paul

I tried your example on VC++. It does not crash but throws boost::bad_expression with message: "Unmatched \{". I think that you should modify your pattern to "(value|default)[^}]*\\{". Otherwise the backslash is ignored (VC++ gives a warning about that) and regex treats '{' as the start of the bounds operator "{}" - as result a closing '}' is expected.

The boost::regex class is crashing when I construct it with some regular expressions. For example: "(value|default)[^}]*\{" will crash and "value|default" does not.

Is this a bug, or am I doing something wrong? I am running gcc2.96 and boost1.30.2. I have attached an example src including Makefile.

Thanks in advance,

Paul
