The bug happens also at least on i386 and s390, so I presume it is target
independent.

Authors of patches that caused a regression must be assigned, not simply CCed.

Breaks QT and OpenOffice, apparently. This is really critical, though I'm not comfortable changing the priority ATM.

This is most likely fixed by http://gcc.gnu.org/ml/gcc-patches/2003-10/msg00065.html
At least, the testcase I had distilled from QT works and the smallest testcase
in this PR doesn't create an endless loop anymore.
