I am getting an intermittant failure in this test, and others in #parrot
have confirmed it. The failure is in a Hash PMC, which, after being
frozen/thawed, in some cases does not return the data that was put into
the original hash.
The test is supposed to output two lines of similar numbers, as follows:
1 2 3 6
1 2 3 6
There are apparently 3 possible outcomes. The first is that the hash
returns the same data that was put into it, and thus the second line of
output is "1 2 3 6". This happens about 80% of the time. The second and
third outcomes are failures, which look like:
1 2 3 6
3 6 Null PMC access in get_integer_keyed()
current instr.: 'test' pc 125 (t/pmc/freeze_25.pir:45)
called from Sub 'main' pc 42 (t/pmc/freeze_25.pir:13)
and
1 2 3 6
Null PMC access in get_integer_keyed()
current instr.: 'test' pc 105 (t/pmc/freeze_25.pir:38)
called from Sub 'main' pc 42 (t/pmc/freeze_25.pir:13)
(the difference being whether the "3 6" is printed or not.)
I have bisected this issue, and it was introduced in r34127.
