2005-01-21 Jeff Johnston <jjohnstn@redhat.com>
* linespec.c (collect_methods): Don't do special processing for
destructors as this will be handled in find_methods.
(find_methods): Fix ctor check to also check for dtor.
* testsuite/gdb.cp/constructortest.exp: New test.
* testsuite/gdb.cp/constructortest.cc: Ditto.
* testsuite/gdb.cp/templates.exp: Change break of dtor to
be fully quoted.
