'zsh -ic exit' hangs

[Mikael Magnusson]

I was just testing around trying to find out which part of my startup
files take the longest when i stumbled upon this bug,
zsh -ic exit
this is the end of an strace run
mmap2(NULL, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0xa2438000
mmap2(NULL, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0xa2434000
mmap2(NULL, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0xa2430000

What version of zsh?  I can't reproduce this with 4.0.6, 4.2.5, or
4.3.0-dev.

Can you reproduce it with "zsh -fic exit"?  If not it probably results
from something in your startup files.

I can't reproduce it:

{pts/3}% zsh -ic exit
{pts/3}% echo $ZSH_VERSION
4.2.5

any special settings in zsh{env,rc}? Does it happen with zsh -ifc?

Hmm, no, it only happens without -f. I'll experiment a bit with my
.zshrc and see if i can figure out what it is.

apparently this is the culprit,
alias exit=' exit'
(i have that so exit doesn't get saved in the history)

    Try this:

    alias exit=' "exit"'

    I'm not sure if the problem is an infinite loop while expanding
"exit" :??? Anyway I always do the above to avoid problems, because
"exit" may be aliased previously. The double quotes ensure you're
using the unaliased version.
