Please post _complete_ short examples of your code: I would hazard a guess
that none of us try to debug a C code before looking at the source. Trying to
follow the ret of your post is an absolute waste of time.

(It is possible that the sgi compiler has a bug: in which case somebody will
recognize the symptoms. But, if that is what you are hoping for, why
crosspost to comp.lang.c????)

I do not see why you thought 0 == 1. With logic like that, it is not
surprising that your code does not work ...

(Okay, okay, I am irritated because you expect us to be mind readers. But the
point is that if you are sending a post all over the world: please be very
careful about what you write!!!)

Looks like you have uncovered an heisenbug :-) (`You cannot simultaneously
look for a bug and find it')

Seriously, this is usually a sign of memory corruption somewhere: try to
compile your program with all warnings turned on, _and_ do not ignore any
warning (You did not say whether there were any warnings). Check every memory
allocation and pointer use: it is impossible to say what the problem is from
what you have described.

Which are almost completely useless without more information. For all I know
you may not have declared G_northing_to_row, or misdeclared it.

As these are not answers nor concrete suggestions, I am not emailing them.
