[Boost-users] Trap in regex library (help requested)

From: Marty Eaves (Marty.Eaves_at_[hidden])

Hello,

 

I am having an issue using the regex library.  I am developing in VC7
and this issue occurs with both Boost 1.33.0 and 1.33.1.  I have
recently tried to start retrieving capture information in the regex
matches by using the match_result and sub_match classes.  In order to
use these classes, the compile flag BOOST_REGEX_MATCH_EXTRA is required
to be turned on (enabled in user.hpp).  With the library is built with
this flag on, I will get the following trap when the method calling
regex_match() returns. 

 

An unhandled exception of type 'System.NullReferenceException' occurred
in tg12.exe

 

Additional information: Object reference not set to an instance of an
object

 

This exception appears to occur in the cleanup logic of the
~match_results() destructor.  I have yet to make any changes to the code
to use the match_results object.  In other words, the code I am using
worked previously without the BOOST_REGEX_MATCH_EXTRA flag enabled.  Are
there any compiler options required?

 

The stack trace is below.  

 

Thanks, Marty
