Sure. I tried this patch
+++ cc-engine.el 2008/04/01 21:41:21 1.56.2.11
but it made no difference; it is still slow, and when I examine the
stack, it is the same stack trace. The file loads in 2 seconds in
fundamental mode, but takes about 2 minutes in C++ mode. I should
have mentioned that this is a preprocessed C++ file, with many
compiler directies, such as #line 1 "somefile.h", and I now think the
problem is provoked by the compiler directives.
If I globally replace the #line stuff like so:
#line 1 "some_file.h"
-->
s = "some_file.h"
the file loads in about 7 seconds.
