Perl segmentation faults with no output on this input (input broken into

Yes, I know this isn't a legal perl program.
Removing "jfw|" from the input makes perl produce this message:
Out of memory!
A longer input, more than double the size of the one above produces this
output from perl on file descriptor 2 prior to death by segmentation
fault:
Next token is 311 (PATTERN)
Reducing 0 values via rule 39 (line 310), state stack now 0 1 2
Entering state 9
Next token is 311 (PATTERN)
Shifting token 311 (PATTERN), Entering state 60
Reducing 1 value via rule 107 (line 525), state stack now 0 1 2 9
Entering state 80
Reading a token:
Ok, so maybe I'll write my program some other way, but perl shouldn't core
dump on this, especially since it originally happened to me inside an
eval. Errors inside an eval should be recoverable ... Oh well.
Enjoy,
