Re: out of memory error after "edit-command-line"

Hi again,

Update:

Tried to isolate what causes the 'out of memory' errors and found that if
I added quotes the error stopped.
  CL=${(0A)"$(< /proc/$P/cmdline)"}  # OK
  CL=${(0A)$(< /proc/$P/cmdline)}  # out of memory error

I had another script and it worked without the quotes. Compared the two
and found the other script had the option 'extendedglob' set. After adding
the option to the script I attached in the original email the 'out of
memory'
errors stopped when there are no quotes.

Not sure what globbing has to do with this. Hopefully someone can
enlighten me. But even so, should zsh ever fail with an 'out of memory'
error? Again, it only happens after exiting 'edit-command-line'.

Regards,

Jim
