STL crashes are usually caused by a bug somewhere else, that corrupts 
STL's private data, most often trees. I've seen that before, and if you 
don't have Valgrind, you're quite doomed.

Do you know any software that could help you debug ?

Another approach is to cut elements of the patch while making sure that it 
still crashes. Then we will know the bug to be in a smaller subset of 
GridFlow's code.
