     Type:  Bugs                     |      Status:  new        
Milestone:  Boost 1.36.0             |   Component:  regex      
  Version:  Boost 1.35.0             |    Severity:  Problem    
 Keywords:                           |  
-------------------------------------+--------------------------------------
 I've been using Boost.Regex with Borland's Turbo Pascal
 2006 compiler. A core code example is included below. The objective is
 to use Boost.Regex in a console application.

 The problem is that the compiler in about 50% of runs fails
 with a 'Error 1004: Fatal Internal Compiler Error' unless
 I do one of the following:

 1) Build a windows Single Document Interface application as opposed to a
 console application.

 2) Include <boost/filesystem.hpp> before <boost/regex.hpp>, as
 demonstrated below.

 Brgds,

 Rune

         bool b = boost::regex_match(s,r); // should evaluate to

              // first time around, change ',' (comma) to '.'
              // (dot) in the declaration of the string s and
              // recompile.

         return 0;
