I'm using GPC 19991030. I'm having a problem with the following code fragment:
shared_data^.compr[J].awel:=[];
which does not result in awel becoming the null set (it retains its existing values). If I change this to:
shared_data^.compr[J].awel:=[1]-[1];
then awel does become the null set.
shared_data is a large complicated record. compr is an array of a fairly simple packed record and awel is a set of 1..120.
I have tried hard to produce a simple test problem to demonstrate the problem but sadly all my test cases work perfectly. Anybody seen anything similar or any suggestions as to anything else I should investigate?
