subtest 41..44 are in sub 'test_gc'
I extracted these and ran them separately - PASS
subtests 34..40 are in sub 'test_equality'
I added these (so 34..44 became 1..11) - PASS
The test passes after running make world/make test. It also passes make
corevm/make coretest using g++-4.5 with --optimize and with gcc-4.5 (with
or without --optimize) and on i386 (32 bit) versions of Ubuntu and also
with Ubuntu 10.04 amd64 with g++-4.4
So it only fails on 64-bit Ubuntu and Kubuntu 10.10 with g++-4.5 after
running make corevm, before running make (world).
At this stage I am not sure if this is a bug in the compiler (?),
something in my setup, or a fundamental problem that it is picking up in
parrot.
I did a new clone of parrot just in case and I got the same results with
Ubuntu 10.10 amd64 (g++-4.5) - RELEASE_2_10_1-477-gfa56f62 and again with
RELEASE_2_10_1-490-g3cfeb72
