           Summary: [13 regression] test case g++.dg/modules/loc-prune-4.C
                    fails

g:069f46c71e9432eda3d48a366e5c2a750cf8d612, r13-1506-g069f46c71e9432

I am only seeing it on power 7 BE with -mcpu=power7 and for both 32 and 64 bit.

That is the commit where this test case was added but it was during a time when
the build failed for me on power 7 from r13-1457-g10b502fb78351a through
r13-1603-g415d2c38edadf9 so I am not absolutely sure that is where it started. 
>From the test results mailing list it is failing on other architectures, too.
