This is master as of right now, configured with:

./configure --enable-checking=yes,glyphs

src/emacs -Q

xterm.c:7753: Emacs fatal error: assertion failed: time <= X_ULONG_MAX

$1 = 4294967295

X_ULONG_MAX looks very 32bit-ish :-)

(why this started happening just now I donʼt know, that assert has
been in for ages)
