Thanks for the report, although this problem has already been fixed in the
75 alpha versions. If you would like, you can obtain a 75aX binary through
one of two methods:

1. /ctcp q cdcc list - on efnet
2. ftp://brian.got.net/pub/BitchX

glibc and libc5 bins are available. Please keep in mind these are test
versions and are not stable. Thanks again for the report and the patch.
Keep up the good work.
