Re: Some files that CEDET cannot parse and produce errors

Hi Eric and Alex,

I think asking you to download my .emacs.d and linux repo is probably too
much.

The easiest way to reproduce this error is from plain Emacs:

*emacs -q*
After Emacs starts, activate semantic mode: M-x semantic-mode

Then open jiffies.h

Then M-x semantic-lex-test

Error happens at line 256:



*hif-shiftleft: Arithmetic errorParsing jiffies.h (LL)...Idle Parse Error:
"#<buffer jiffies.h> - Arithmetic error"*

This error keeps repeating:

*Error running timer `semantic-idle-scheduler-function': (arith-error)*

Emacs version: Compiled from emacs-trunk. I hope you use this version as
well. I think semantic should be the latest version with emacs-trunk.

If you try to reproduce, please do not let Semantic read from your
semanticdb.

Hope that helps,

Regards,

Tu.
