--- Comment #7 from Fred Krogh <fkrogh#gcc at mathalacarte dot com> 2013-03-16 21:44:46 UTC --- As mentioned in my first post, I am compiling with -fcheck-bounds. The errors are occurring in a subroutine inside what at the moment is a main program. That subroutine has no arguments. As this is code in the process of being developed, I have had run time errors for indexes being out of bounds. It turns out as a result of thinking more about the problems I'm dealing with (algorithmic issues) this part of the code is likely to disappear. I do appreciate others trying to find my problem, that is very nice. I was posting in the hope that I might help someone in finding a compiler bug.
