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
