I have managed to reproduce the problem on the small test case on mips32, but
the test is architecture independent and should probably fail on many other
ports without
Patch has been tested with DejaGnu gcc test suite on mips32r2 cross compiler
and bootstrapped and tested on
x86_64 native compiler.
