Now that my flu is abating, here's a small test case. Could someone please
append this to bug #465's info as a preferred test case? It's probably
even a fair test for parrot itself.
If you want the DUMPSTACK routine, let me know otherwise just looking at
the stack should be enough to tell that it went screwy. The hang occurs as
you're re-reading the stack after this runs, one of the restore Sx
instructions hangs.
set I3, 0
set S3, "I am the very model of a moden major general I have
information animal, vegetable a
nd mineral."
OUTER:
set S0, S3
inc I3
set S1, ""
eq I3, 10, END
set I5, 0
LOOP:
length I0, S0
le I0, 0, ENDLOOP
substr S1, S0, 0, 5
sub I0, I0, 5
substr S0, S0, 5, I0
save S1
inc I5
branch LOOP
ENDLOOP:
branch OUTER
END:
save I5
#bsr DUMPSTACK # It hangs in here, the stack is already very corrupt
# Ask if you need this.
end
