Hi,

I'm seeking help for the following problem, using the regex library:

the following line of code is meant to assist in parsing urls:

boost::regex exp("(?is)(https?)://([^:/?#]+):?(\\d{1,5})?/?([^?#]*)?\ 
\??([^#]+)?#?(\\w*)");

It runs fine in a linux environment, however if compiled with VC9 on  
windows, it fails with:

First-chance exception at 0x7c812aeb in test.exe: Microsoft C++  
exception:  
boost 
::exception_detail 
::clone_impl 
<boost::exception_detail::error_info_injector<boost::regex_error> > at  
memory location 0x0012f768..

I thought that the expression might be too long, and indeed if I  
shorten the above line to:

boost regex exp("(?is)(https?)://([^:/?#]+):?(\\d{1,5})?/?");

it runs fine on windows as well. Any help on what the cause of this  
can be, would be appreciated.

Regards,
==Adam
