CVS commit: src/lib/libc/time

[Christos Zoulas <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Wed Feb 17 17:25:55 UTC 2010

Modified Files:
        src/lib/libc/time: localtime.c

Log Message:
Fix a bug reported by Gene, and debugged by Robert Elz. fsck_ffs can coredump
if the timezone file fails to load, due to late initialization of sp->goahead
to false in tzload, causing localsub to return NULL in the "cannot happen"
case. The fix is belt and suspenders:
        - initialize sp->goback and sp->goahead very early in tzload
        - replace all malloc calls with callocs, and remove the bogus
          casts (it is not the 70's anymore!)
