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 error
Parsing 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,
