Greetings,

I have noticed Clang going into an endless loop and eating more and more memory
while compiling qdm2.cpp from ScummVM project. The following link points to the
file:

http://scummvm.svn.sourceforge.net/viewvc/scummvm/scummvm/trunk/graphics/video/codecs/qdm2.cpp?view=log

The problem only occurs when compiling with -O2 (and probably higher)
optimisation level. Everything's fine with -Os.

This is with LLVM and Clang updated from SVN today, December 24th, 2010, built
and used on Mac OS X 10.6.5. Same with ScummVM; SVN updated today.

If you would like me to do more testing, don't hesitate to contact me.

Kind regards,
Adam
