Subject: Use ptrdiff_t, not int, for stack sizes
X-Git-Tag: emacs-26.0.90~521^2~481
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=b867eb8ecf67e9fb8167d950316ba762ac561b1c;p=emacs.git

Use ptrdiff_t, not int, for stack sizes

* src/thread.c (invoke_thread_function):
* src/xterm.c (x_cr_export_frames):
Don’t assume SPECPDL_INDEX fits in ‘int’.
