Hi,

In Src/hist.c on line 1668 there is a NULL pointer dereference because GNUcanonicalize_file_name returns NULL on some errors.


In attachment you will find a small patch that fixes that bug.

If you want to reproduce it you can do (under GNU/Linux) a simple: zsh -c'a=(a /b) ; echo ${a:A}'


Thanks
