116	intermittent failure of t/pmc/freeze_25.pir	Infinoid		"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."	bug	closed	normal		none		medium	fixed
