Hello Matthew,
I know you wanted to have a look into the prompt-issue (#337406), so if you
plan a new
release, here is another error with fix, a kind debian user found (and
analysed):
http://bugs.debian.org/342480
Greetings
Bernd
Package: ircii
Version: 20051015-1
Severity: normal
Doing /set -irc_encoding command makes ircii segfault. Also set
-display_encoding and set -input_encoding nukes.
I built a unstripped deb package and used the binary with gdb:
/set -irc_encoding
Program received signal SIGSEGV, Segmentation fault.
0x0fe5bad4 in strlen () from /lib/tls/libc.so.6
(gdb) bt
#0 0x0fe5bad4 in strlen () from /lib/tls/libc.so.6
#1 0x0fe006f0 in iconv_open () from /lib/tls/libc.so.6
#2 0x10046c74 in set_irc_encoding ()
#3 0x1004784c in set_var_value ()

#9 0x100270d4 in irc_io ()
#10 0x10027c64 in main ()
(gdb)
The bug is in source/translat.c functions set_irc_encoding,
set_display_encoding and set_input_encoding. These functions pass the
NULL 'enc' to iconv_open() that in turn passes the given pointer to
strlen() -> boom.
Fix is simple, add check for NULL string pointer before passing the
argument to iconv_open. Corresponding else-statement should probably NULL
the matching _encoding variable (so user can really disable the
encoding).
