instant core dump with latest CVS

[Adam Spiers]

My newly-compiled zsh core-dumps as soon as you run it.  With -x:

  +/nfs-home/adams/.zshrc:269> promptinit
  +promptinit:9> prompt_themes=( )
  +promptinit:10> typeset -gU prompt_themes
  +promptinit:11> typeset -g prompt_theme
  +promptinit:192> [[ -o kshautoload ]]
  +promptinit:192> promptinit
  +promptinit:1> emulate -L zsh
  +promptinit:2> setopt extendedglob
  +promptinit:3> local ppath= name theme
  zsh: 15701 segmentation fault (core dumped)  ~/local/bin/zsh -x

Here's the lengthy stack trace; hopefully it will be enough to track
it down.

Can't reproduce it.  Is this with an older zwc file, perchance?  We had
15030, changing the way for-loops are stored an inthat line there, there
is a for loop...

And I forgot to make sure the zwc version number got incremented for
15030.


Bye

That was it, thanks.

Shouldn't it be incremented now then?

Yes, probably.
