I can reproduce this with the simplifed testcase on powerpc-apple-darwin so this is generic bug 
not effecting only ia64.
Here is the backtrace I have:

Also can reproduce with this on i686-pc-linux:
register int foo __asm__ ("ebx");

>From Phil's regression hunter with that testcase: Search converges between 2003-08-18-trunk 
(#376) and 2003-08-19-trunk (#377).

You just need the option -funit-a-at-time flag to reproduce this.
