[Bug target/18485] New: [4.0 regression] mmix-knuth-mmixware testsuite failure: g++.dg/lookup/forscope1.C

[hp at gcc dot gnu dot org]

With LAST_UPDATED: "Sun Nov 14 05:49:38 UTC 2004" I get:
FAIL: g++.dg/lookup/forscope1.C (test for excess errors)

With the message in g++.log being:
/gcc/testsuite/g++.dg/lookup/forscope1.C: In function 'void Go()':
/gcc/testsuite/g++.dg/lookup/forscope1.C:25: error: NOTE_INSN_BASIC_BLOCK is
missing for block 0
/gcc/testsuite/g++.dg/lookup/forscope1.C:25: error: NOTE_INSN_BASIC_BLOCK 8 in

    (nil))
/gcc/testsuite/g++.dg/lookup/forscope1.C:25: internal compiler error: in

Last known to work on: "Fri Jul 9 02:34:14 GMT 2004".
Known to work on unspecified 3.4 and 3.4 checkouts.
Known to fail on: "Sat Sep 11 14:54:38 GMT 2004".

Errors with similar appearance in the past have been flaws
in the basic-block machinery.

g++.old-deja/g++.niklas/t132.C and g++.old-deja/g++.other/singleton.C of the
same test-run seem to be the same bug judging by the g++.log contents.
