I cannot reproduce this. Does the buffer contain anything else in
addition to the text you've shown? Does it happen in "emacs -Q"?
I invoked "emacs -Q", then typed
C-x C-f headerhang.h
#define AVL_iter(
At that point, Emacs was responsive as I'd expect. Are you doing the
same to reproduce the problem?
Thanks.
