             Bug #: 56322
           Summary: text/template and testing/quick FAIL on 32-bit
                    Solaris/SPARC
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0

There are two remaining libgo tests that FAIL on 32-bit Solaris/SPARC, and they
seem to be related:

FAIL: testing/quick

Illegal Instruction

I couldn't get a useful stacktrace out of gdb 7.5, so I'm using dbx and mdb
instead to get at least some information:
