Any suggestions ? Of course I can always use the workaround.

Unfortunately no other suggestion. GPC's set code is not very reliable, and esp. set addition is known to be buggy. :-( Since there don't seem to be many programmers using sets (besides you and me), this problem doesn't have very high priority on the to-do list...

So, you'll probably have to live with workarounds for awhile -- unless you want to hack GPC itself and fix the bugs...
