Folks,
When using bc version 1.05 that comes packaged with the SuSE 7.0 release, the
code segfaults if a string longer than 127 characters is entered.

Segmentation fault
This seems like a simple buffer overflow, and since the program doesn't run
setuid or anything crazy, it's not dangerous, just thought I'd let you know.
Same behaviour with version 1.04.
