Description:
------------
Hi,

Compiling php5-5.5.9+dfsg from the Ubuntu repo's works fine, but when running the php executable, it segfaults due to an invalid pointer.


# ./sapi/cli/php -r 'echo test . "\n";'
test
*** Error in `./sapi/cli/php': munmap_chunk(): invalid pointer: 0x000060060004a200 ***
Aborted (core dumped)


Here is a gdb output:
[New Thread 0x7fffe762b700 (LWP 54760)]
[Thread 0x7fffe762b700 (LWP 54760) exited]
