Emacs hang on heavily templated .H file

When I open up file Sequence.h of the Loki template library (http://
sysinf0.klabs.be/usr/include/loki/Sequence.h?dist=%3Barch=)

in emacs, it hangs when attempting to scroll (C-v) the file around the
time it hits 58%.  When I run top it is shown to be hogging the CPU @
99%.  I believe the cause to be some poor template parsing (bad loop
of some sort?) mechanism in C++-mode.  Is there any way to debug
through something like this?
