Segmentation violation upon opening a particular C++ source file.

Opening certain (rather complicated, template class) C++ files can produce a segmentation violation.

Unfortunately, for legal reasons, I can't attach an example of such file. I also had no luck in producing a simpler file that can trigger the crash.

Attached is a traceback obtained with QtCreator (debugging QtCreator). The message displayed just before crash is

"""
pure virtual method called
terminate called without an active exception
"""
