dc OS X specific glitch

[D. Kevin McGrath]

While working with the below perl script, which is one of the more common 
scripts to implement RSA, I came across some oddness.  When using a key of 
more than 512 bits, there is always a seg fault error.  Also, the attached 
file contains a command which should print out the Lewis Carrol poem 
"Jabberwocky" that I found on the internet while searching for other 
instances of the bug.  I have found it only on OS X, running on TiBooks.  2 
were default 10.2.4 installs with the latest Dev Tools installs, and the 
other had a long time fink install as well.  When running either the script 
or just dc directly on a FreeBSD box, there are no errors at all.  Have you 
had other reports of this problem?

There are other places where the same error has occurred, and it always 
seems to be somewhere in the math libraries, but I can't trace it any more 
than that, and this is the only reproduceable one that I can find.  Any 
ideas?
