It shouldn't be calling wrefresh() at all, ever, since zsh uses
termcap, not curses. The problem seems to be that the function
refresh() is wrongly coming from the curses library instead of zle
with dynamic loading. If you're not using dynamic loading, you
probably won't see these problems (you might see a warning from ld
about pre-empted symbols, though I know loading on the machine I'm
using is a little unusual), which might explain differing behaviour.
Three functions seem to be affected: refresh(), beep() and setterm().
The first is treated in Zoli's AIX dynamic loading patch, but the
others have the same problem. Anyone using dynamic loading under IRIX
6 should try the following patch, which simply sticks a z in front of
the names, and see what happens.
The shell-related building problems from 3.1.5 which IRIX 6.2 had have
gone away, which is why I'm only now in a position to test this (I've
been compiling on an older IRIX 5.3 machine up to now). I'm compiling
with gcc 2.7.2.2 and haven't seen any trouble with sourcing scripts,
so I can't promise this fixes everything, but in my case limited
testing seems to show everything OK with all possible libraries
dynamically loaded, so it certainly seems possible to get it right.
(If anyone's desperate I can make my binaries available via http, but
I'll need to recompile as my DLLs are in a non-standard place.)
