RE: [avr-gcc-list] passing pointers to functions

[Weddington, Eric]

Two things:

1. IIRC, there was a problem with 4.3.0 unless you had the right patches. It 
may not be related to your problem, but we need to know what platform you're 
building on, and what patches are you using. You may need to upgrade.

2. We need to have a compilable test case, preferably as small as possible, 
that shows the error. There is not enough information here to tell you one way 
or the other what is going on with your code.

Honestly I suspect something in your code, and not the compiler.
