Consider the attached code ice.c . When compiled, it is giving an internal
compiler error. I was not able to reduce it any further. Would appreciate if
someone can reduce it further.

> gcc -c ice.c 
ice.c: In function 'd_substitution':
ice.c:23: internal compiler error: Bus Error

Initially, I asked this question on gcc-help
http://gcc.gnu.org/ml/gcc-help/2009-01/msg00109.html . I narrowed down the
problem further and reporting it here.

thanks
