. . .
If someone reading this (not just Bob or me) cares to write up some basic
tests and can make a failure case, I'm very happy to debug and fix the
problem. I'm out of town for a couple of days and may not get to the
tests
for a while, but I will fix the problem unless someone beats me to it.
Does this fit the bill? This fails reliably on my laptop (SUSE 10.1,
gcc 4.1.0) using Parrot r22785 or r22817, but works on my desktop (SUSE
9.0, gcc 3.3.1, also r22817), so who knows what kind of mileage you'll
get?
For the record, hll-dumper-main.pir now works if it loads
hll-dumper-test.pir, but if I compile the latter and load
hll-dumper-test.pbc instead, I see the following problem:
src/pmc_freeze.c:1202: failed assertion 'must_have_seen'
But only on my laptop; it all works normally on my desktop system. And
disassemble doesn't have any problem with the PBC file.
But (on my laptop) if I compile *the same source file* to some other
PBC file name, e.g. using
parrot -o wogga-wogga.pbc hll-dumper-test.pir
and change hll-dumper-main.pir to load wogga-wogga.pbc instead of
hll-dumper-test.pbc, it works again! So something, possibly
freeze/thaw, appears to be infested with Heisenbugs.
And lest anyone think this just affects my laptop, I am seeing three
t/tools/pbc_merge.t failures on my desktop system that are due to the
'must_have_seen' assertion. The complete list of desktop system test
failures is appended. (There are only three failing tests on the
laptop.)
I will keep my eyes open, but I'm hunting for a needle in an
unfamiliar part of the Parrot haystack.
