Description:
------------
Summary : stack-buffer-overflow exists in DateTimeZone stuff which was caught by AddressSanitizer.

I am using Fedora 19's GCC which supports AddressSanitizer.

1. Download and extract php-5.5.3.tar.xz

2. Configure build flags,

   export CFLAGS="-fsanitize=address -O2 -ggdb"

   export LDFLAGS="-fsanitize=address"

3. Build PHP as usual using "make".

4. Running ./sapi/cli/php ext/date/tests/DateTimeZone_clone_basic1.php crashes with,

    *** Testing clone on DateTime objects ***
