This is a great find. Please file a ticket.
My guess is that there is some backtracking in the parser, which explodes
for large values.

It's worth pointing out that Pig 0.9.2 also runs quickly; we only see the
degradation with Pig 0.10.0.
The degradation in performance seems to have a knee as 4 or 5 conditionals
works as expected but as presented, the script takes about 6 minutes at
the GRUNT> prompt after hitting enter; befor
We found the following simple logic will cause very long compiling time for pig
0.10.0, while using pig 0.8.1, everything is fine.
A = load 'A.txt' using PigStorage() AS (m: int);
B = FOREACH A {
days_str = (chararray)
(m == 1 ? 31:
(m == 2 ? 28:
(m == 3 ? 31:
