Re: Pointer Error

[Stuart Rowe <rowestu@xxxxxxxxx>]

I have often seen this happen when other bad things are happining in your
program that destroy the program's internal storage, such as mismatched
parameters, writing past the end of allocated storage with pointers, that
sort of thing.  LIke you declare a variable as 10 bytes and a service
program declares it as 128 bytes and then clears it -- whammo,
unpredictable results will occur.  I actually managed to blow up the
internal RPG error handler once so badly that my job would just disappear!

Might be worth a trip through the source to check on those sorts of things.
