Description:
------------
According to point 9 of php-5.5.12/CODING_STANDARDS the parse_date does not use the emalloc(), efree(), estrdup(), etc. and it does not check if the *alloc was successfully

egrep -A3 alloc php-5.5.12/ext/date/lib/parse_date.c

Maybe it is unimportant but it would be nice if anyone take a look there and say it's ok or not.

I think the whole date directory should be reviewed.

egrep -r -A3 alloc php-5.5.12/ext/date/*
