Actually, I stand corrected. Just to be sure, I did a clean and re-built and it's working now. Mia culpa! Thanks for the information. Chris On 5/23/06, Christopher Hart wrote:

When I received the error, BOOST_REGEX_MATCH_EXTRA was defined both at my program's compile time and when in user.hpp when I built boost. Based on my vauge understanding of that error, my impression was that it was attempting to read memory that had already been de-allocated. Is that consistent with a missing definition (either when the library was built or at my program's compile time)? Or am I missing something?

Thanks, Chris

All:

I'm trying to run the captures example included in the Boost.Regex documentation. When running the captures example verbatim, I get: "Program received signal: "EXC_BAD_ACCESS"."

This is happening on Mac OS X 10.4.6 (Intel) with Boost 1.33.1. This problem seems to be related to the definition of BOOST_REGEX_MATCH_EXTRA - if I don't use captures and leave the macro undefined, other regex functions work fine.

In order to use the extended capture information then you must define BOOST_REGEX_MATCH_EXTRA:

*both when building your application, and when building the regex lib*

If you're linking against the standard bjam built lib's then this won't work: the lib's won't be binary compatible with the BOOST_REGEX_MATCH_EXTRA option. Yes I no this is a pain, but it's a feature that has costs, so I don't want to enable it by default.

John.
