I tried to reproduce this but failed on both 7.4.1-20120718-cvs and
7.5.50-20120808-cvs (HEAD from one week ago).

Does the problem occur if you disable pretty-printing of STL containers?

I don't suppose you could reproduce the error and provide a stack backtrace?
That would be incredibly useful.

Perhaps related, perhaps not, but fyi,
see pr 17614 for an OOM with a backtrace.
