Re: zsh under leopard, screen not executing zprofile, wiping PATH

[André Wobst]

Hi,

I have the same problem for months. Very annoying. Thanks to your  
pointers!!! I recompiled screen to find out where the path environment  
breaks. Its not the window.c.diff but the screen.c.diff patch. The  
path environment breaks as a side effect of the if condition  
evaluation. Any idea what _vprocmgr_move_subset_to_user is needed for?  
Are there any sources available for this stuff? Or do you know a  
proper procedure to report this issue to Apple? I would really like to  
get this issue resolved in some future, as my dev environment for one  
of my projects broke at the leopard update where this issue seems to  
have been introduced. And its just annoying to work around this Apple  
bug ...

Best,


André
