NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

Emacs 18 is currently only available on 32 bit platforms, and there are many places where the code assumes that a pointer will fit in an integer.

I am currently working on a 64 bit version which will fix all these problems.
