Fedora 7 - buffer overflow detected

[Martin Gansser <mgansser k-p-ebert de>]

hi,

i have tried to compile beast-0.7.1 on Fedora 7, that works
with the beast-guile.patch.
But when i start beast, a "buffer overflow" stop the program.

this is the output from gdb
(gdb) r
Starting program: /usr/bin/beast 
*** buffer overflow detected ***: /usr/bin/beast terminated
