I can't verify this on 32-bit x86 Linux.  Does it go away with a 'make clean' 
or a 'touch src/dynpmc/*.pmc; make'?

My usual test procedure starts with make realclean, svn update, perl Configure.pl --test (+ other options), make world, make html, make smoke, make nqp_test, make fulltest.

I have built and tested with gcc and g++ (in separate directories - parrot and g.parrot) and the test has failed at r40685 (gcc), r40686(g++), r40688(gcc) and r40690(g++).

All the tests were on Ubuntu 9.04 amd64.

I will test later today on Ubuntu 9.04 i386 (needs a reboot)

I got the following results from r40691 - Ubuntu 9.04 amd64 (g++)
(tidied up a little - it was jagged)

I just tested on Ubuntu 9.04 i386 and the test PASSed.

All tests PASS (pre/post-config, smoke, nqp_test, fulltest) at r40716 - Ubuntu 9.04 i386 (g++)

The test still fails on Ubuntu 9.04 amd64 at the same revision (r40716)

[mikehh]

bisecting: the test passes in r40679 but fails in r40680

furthermore with an optimized build both test 6 and test7 FAIL without the optimize only test 6 FAILs

I initially tried to build with g++ but the build failed (fixed in r40686)

I then did:

make realclean
perl Configure.pl
make
make test TEST_JOBS=5 -> PASS
make testr TEST_JOBS=5
...
#   Failed test 'inherited add'
#   at t/dynpmc/foo.t line 132.

make: *** [testr] Error 1

repeating with:

make realclean
perl6 Configure.pl --optimize
make testr TEST_JOBS=5

it then also failed test 7 - Failed tests: 6-7

NB. the .pbc files generated by make testr in t/dynpmc were not removed by make realclean (fixed in r40719)

I think this should be resolved as of r40736.
