           Summary: guality_check hangs indefinitely on Tru64 UNIX
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite

The guality_check in g++.dg/guality/guality.exp hangs indefinitely on Tru64
UNIX
V5.1B, hanging the whole testsuite run.  It seems to be a gdb issue, but still
occurs with CVS gdb.

Here's what happens when I use a simple looping test program as target of the
procedure used in guality.h:

> gdb -nx -nw --quiet 
(gdb) set height
Argument required (integer to set it to.).
(gdb) set height 0
(gdb) attach 216346
Attaching to process 216346

(gdb) set guality_attached = 1
No symbol table is loaded.  Use the "file" command.
(gdb) b 1
No symbol table is loaded.  Use the "file" command.

In g++.log, I find that the test is run with the regular timeout of 300
seconds,
but this has no effect for some reason.  Might be a bug in expect (5.38.2).

The guality_check test in gcc.dg/guality/guality.exp isn't affected for some
reason.

I'll disable the test on Tru64 UNIX until this is resolved.

This is somewhat related to PR testsuite/46529, but there the timeout does
work.
