[PATCH] fix git-checkout-cache segfault on parisc

Browse Source 
The index cleanup code is executed via atexit() which is *after* main
has completed, so the stack allocated cache_file has gone out of scope.
Parisc seems to use stack in the destructor functions, so cache_file
gets partially overwritten leading to the predictable disastrous
consequences.

[jc: Just to make sure, I audited other users of the function
 hold_index_file_for_update() to make sure they do not have this
 problem; everybody else uses non-stack cache_file structure and
 is fine.  Thanks, James.]
