             Bug #: 52342
           Summary: 64-bit go.test/test/chan/doubleselect.go times out on
                    Solaris/SPARC
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: ian@airs.com
        ReportedBy: ro@gcc.gnu.org
              Host: sparc-sun-solaris2*
            Target: sparc-sun-solaris2*
             Build: sparc-sun-solaris2*


During all my Solaris/SPARC bootstraps, a single go.test testcase consistently
times out:

Running target unix/-m64
FAIL: go.test/test/chan/doubleselect.go execution,  -O2 -g 
WARNING: program timed out.

This happens only in the 64-bit case.  Even on a completely unloaded machine, I
find

> LD_LIBRARY_PATH=../../../sparc-sun-solaris2.11/sparcv9/libgo/.libs:../../sparcv9 timex ./doubleselect.x 

real        2:26.36
user        2:28.07
sys            2.54

which is dangerously close to the default timeout of 300s.

The 32-bit version is way faster:

real           2.70
user           3.01
sys            2.19
