I plan on using GCC more (Linux and Windows) and I was wondering if there\'s an equivalent of the MSVC debug heap and the STL checks available for the GCC CRT and STL.
The STLport version of the standard library at http://sourceforge.net/projects/stlport/ has a debug mode, which I used to use, and which is recommended by Scott Meyers in Effective STL. I haven't used it for several years now however, so I can't vouch for the current state.
There is also a thread about GCC STL debugging here, but I once again I can't vouch for the info it gives.
