Daniel wanted the stack printed upside down. Perhaps he 

feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

Stack dump:
0.	Program arguments: clang clang_crash_Iw2Osj.mi 
1.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: parsing function body '_mm_cvtpi16_ps'
2.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: in compound statement ('{}')
Abort
