I already filed this as bug 21541 when it started failing.

Forgot.

Bug 21541 isn't tagged to the hppa target.  Generally, I find target
searches the easiest way to find target related bugs.

The bug didn't seem target-specific so I didn't enter target fields.  
Normally I search for the testcase name (actually, in my GCC list folders 
so as to locate any recent discussion of it other than in Bugzilla as well 
as gcc-bugs traffic) when entering new bugs for testsuite regressions; 
this also shows if other targets have results on gcc-testresults with the 
test failing.
