Here is what the problem turned out to be. It had nothing to do with
a null terminated string. I had a field that was supposed to be a
single line. I had the properties for this field defined as multi-
line and dynamic sizing. But there was only enough room for a single
line. Then, Gremlins would queue up two newline chars occasionally.
This is what was causing the problem.
I was able to duplicate this by simply entering anything in the field
and then make sure that I entered two linefeeds. One linefeed char
did not cause the problem. Then after entering the two newline, I
would do some calculation based on this field.
Crash! The strings were always null terminated but included two
newline chars. Does this sound like it should generate this error?
Whether or not is sounds right, it in fact does.
I just made the field single line and the problem went away.
