Comment:
Today I again tried to merge this branch into trunk. The failure in
''t/library/test_more.t'' somehow cleared itself up -- but I got a
different failure in ''t/compilers/pct/complete_workflow.t''.

This error is shockingly similar to the one I have reported in TT #1393,
wherein, since r43211, ''t/compilers/pge/pge_examples.t'' fails when run
through the harness with `--gc-debug`. Both errors start out with:
{{{
# src/gc/api.c:245: failed assertion 'PObj_is_PMC_TEST(obj)'
}}}
The first 16 frames in their backtraces show Parrot calls in the same
sequences:
{{{

}}}
... and there are plenty of similarities in the remaining 16 frames. The
branch I am attempting to merge into trunk was forked from trunk at
r43163, ''i.e.,'' before r43211. The branch passes all its own tests, so
the errors reported above are almost certainly due to recent changes in
trunk, with r43211 again a likely culprit.
Thank you very much.[[BR]]
