I tested this patch locally, and it reduced the fallout to two
instances. On running 'make t/spec/S12-attributes/class.t' after all the
tests have finished successfully:

ok 30 - good error message
# FUDGED!
src/call/pcc.c:613: failed assertion 'PObj_is_PMC_TEST(sig_pmc)'

The other is t/spec/S10-packages/basic.t which has been failing for
quite some time now.

Cheers,
