A problem now seen by two of us with recent Cygwin installations:
mine was updated to `current' status last week. However, I don't think
this is new since I've been seeing it on my own setup for a while.
Zsh uses `dllwrap --export-all-symbols' to link against it's own DLL's.
On the systems in question, dllwrap failed to identify the last symbol
exported from the main dll (zsh.dll) against which all the other DLL's
are linked. The symbol in question is `zwarnnam'; we've verified it
really is the last symbol by adding a dummy one later in the alphabet,
and the problem goes away. (This is an easy workaround so consequently
finding a real fix isn't a high priority for us.)
It sounds like if this is fundamental lots of people would have fallen
over it, but I've no idea what else might be relevant.
Anyway, on systems where it does trigger, it will show up by downloading
zsh 4.2.0 from ftp://ftp.zsh.org/pub/ and trying to compile with default
options. You will see warnings about failures to find the symbol
zwarnnam when linking DLL's. (The failure seen by users is a crash on
an attempt to print warning messages form libraries. Running `vared
nonexistentvar' form the installed shell will do this.) We haven't
narrowed it down any further.
If you (the Cygwin people) need more information, it's probably best to
prod zsh AT sunsite DOT org (this list runs qconfirm but you only need to
confirm once).
