vector_capacity:test03() failing on mips-irix6

[Kaveh R. Ghazi]

On mips-irix6, I've been seeing errors in libstdc++-v3 testcase
23_containers/vector_capacity.cc since around 11/17 on the trunk and
around 12/5 on the 3.2.x branch up through today:

http://gcc.gnu.org/ml/gcc-testresults/2002-11/msg00658.html
http://gcc.gnu.org/ml/gcc-testresults/2002-12/msg00228.html

This coincided with the installation of the following patch in each
place respectively:

 >             Benjamin Kosnik  <bkoz@redhat.com>
 >             Gabriel Dos Reis  <gdr@integrable-solutions.net>
 > 
 > 	PR libstdc++/8230
 > 	* include/bits/stl_alloc.h: Use builtin_expect for the most
 > 	obvious limit checks.
 > 	(__default_alloc_template::allocate): Check for null, throw
 > 	bad_alloc.
 > 	* include/bits/vector.tcc: Formatting tweaks.
 > 	* include/bits/stl_vector.h: Same.	
 > 	* testsuite/20_util/allocator_members.cc (test02): Add.
 > 	* testsuite/23_containers/vector_capacity.cc (test03): Add.


When I ran vector_capacity.exe under gdb, sure enough it dies in the
new test03.  Here's a backtrace, any thoughts?
