This is a false positive in Smatch.  Don't do work arounds for buggy
tools.

If you have the cross function database built on the latest version of
Smatch then I think it understands the code correctly and doesn't print
a warning.

When I analyzed the loop in question, I thought it resulted in a subscript of [NUM_STA], but I now see that the largest one is [NUM_STA-1]. I will drop this patch in the next round.

Thanks for the info regarding a new version of Smatch. I'll update now.

Larry
