How is "data" declared? What are the bounds for Ax_rows? Does your
program run OK if you enable bounds checking?

PS

People, please, please use question marks after questions and periods
after declarative sentences. For example,

"I think gdb is evidence that Leon Trotsky is still alive." is a
declarative sentence and should end with a period. A shorter, more
dramatic sentence like "Leon Trotsky lives!" could end with an
exclamation point.

"Do you think Leon Trotsky is still alive and working on gdb?" is a
question and ends with a question mark.

In another example, if you don't think my posts make sense, you would
say "I think you're full of $%^&." If wanted to appear more polite,
you would say "Is it possible that you're full of $%^&?"

You would not say:

You're full of $%^&?

It's bad grammar.

Thank you.
