[php-maint] Bug#483461: php5-cli: use_embedded_timezonedb.patch php5 patch causes segmentation faults when tzdata not installed

[fatz at fatkids.com]

Package: php5-cli
Version: 5.2.6-1
Severity: important

When /usr/share/zoneinfo does not exist, this patch attempts to free() on
unallocated memory, causing PHP to cease functioning.  The problem comes
from:
314                     free(ents);
Earlier, ents set via:
110               count = php_scandir(name, &ents, index_filter,
php_alphasort);  

Name is typically "/usr/share/zoneinfo".  If the directory
/usr/share/zoneinfo does not exist, ents is set to -1, but line 314 still
attempts to free it, causing the problem.
 
tzdata does not appear to be a requirement for php5, so there is no
guarantee that this directory would exist.
