Fix for 1.33.1

The example regexes from the reproducer all unambiguously SIGSEGV boost_regex,
with or without the patch in file 291643.  This patch contains one additional
change that fixes this.  I checked that it introduces no new regressions, and
that with this patch, reproducer testcases all throw exception as they should.

Comment 17 Petr Machata 2008-01-16 20:44:39 UTC
(The patch from comment #16 is relevant for boost distributed with RHEL-5 as
well as Fedora 7.  Fedora build is spinning right now, taskID=353614.)
