[Mspgcc-users] gcc 'Internal compiler error'

[Takahashi, Chris]

I'm getting an Internal compiler error when I compile part of the code I am
working on.  Attached is a simplified version of the code.  When I compile
this code with gcc for x86 it comes out fine so I think this is a MSP430
specific problem.  I've added a #define so that if you define _COMP_WORK
you'll get a version of the code which is almost the same and performs the
same function but does not create the error.  I hope this helps narrow down
the location of the bug.  Below are the commands I used to generate the
error.  Attached is the source and the preprocessed source.

Thanks
