new completion and dynamic loading weirdness

["Andrej Borsenkow" <borsenkow.msk@sni.de>]

I have been using dynamic modules on ReliantUNIX for quite a bit without any
problems. Suddenly, whent trying to test new competion, I got absolutely
weird behaviour:

bor@itsrm2:/tools/src/zsh-3.1.5-pws-9/Functions/Completion%> zsh -f
itsrm2% setopt extendedglob
itsrm2% fpath=( $PWD )
itsrm2% source init
itsrm2% cd <TAB>zsh: illegal hardware instruction (core dumped)  zsh -f
bor@itsrm2:/tools/src/zsh-3.1.5-pws-9/Functions/Completion%> dbx =zsh

It happens on both 5.43 and 5.44 in 32 or 64 bit mode.The error differs (bus
error, seg fault etc). Statically linked zsh is fine.

The stack is of no use. It suggests, that zsh tries to run startup code
(_rt_boot & co are part of /usr/lib/libc.so.1) - but why? And what has it to
do with new completion?
