Bug#385580: gcc generates incorrect code on s390

reassign 385580 gcc-4.1
clone 385580 -1
reassign -1 coreutils
severity 385580 important
forwarded 385580 http://gcc.gnu.org/PR28146
retitle 385580 [4.1 regression, fixed in 4.2] gcc generates incorrect code on s390
tags 385580 + upstream
tags 385580 + fixed-upstream

according to PR 28789 this cannot be fixed in 4.1.  Please either
build using gcc-3.4 on s390 or use the workaround mentioned in the
redhat report.
