emacs/src/mem-limits.h, branch pending Emacs is the extensible, customizable, self-documenting real-time display editor. Fix crash due to non-contiguous EMACS_INT (Bug#10780). 2012-02-20T23:09:58+00:00 Paul Eggert 2012-02-20T23:09:58+00:00 310f5bd4294ec3624b425e2c27da6fc730d0e928 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it. (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0. It's useless in that case, and it can cause problems on hosts that allocate halves of EMACS_INT values separately. Reported by Dan Horák. Diagnosed by Andreas Schwab in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>. * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where UINTPTR_MAX >> VALBITS == 0. This is required by the above change; it avoids undefined behavior on hosts where shifting right by more than the word width has undefined behavior.

This follows up to the 2011-05-06 change that substituted uintptr_t
for EMACS_INT.  This case wasn't caught back then.
