Emacs freeze after typing #define

[roastercode]

define LedOn digitalWrite

then it freeze at spacebar hit time

[lpaseen]

I see the same issue and the trigger seems to be when you enter "("
#define foo bla/(
when I enter ( it just hangs, cpu goes to 100% and only way out is ^g or to kill it
Even more to it, create a .ino file with that content and it hangs the same way when opening the file.

[conorpeterson]

This is a bit of a killer for anybody who wants to:
#define CBI(port, bit) //etc.

That's a bummer (as is my delay in responding here). I've never been able to reproduce this, so if anyone is still seeing this issue it would be much appreciated to add some details about which version of emacs you're using and any extra modes that are active.

This is probably related to #5.

Get a little info:

Here's a simpler backtrace. The following is from opening a fresh arduino-mode buffer, and typing #define foo C-q (:
