Any attempt to prevent bugs or make a piece of software more fool-proof is good ... but having success in this is even better

1. YES, it crashes if made VALID
2. Well, it also crashes as-is INVALID - thus the "fix" doesn't work
3. There is a horrible bug in VALX becuase of this. IIRC you were the linker lover and expert - don't you care ?
4. The bug causing the crash is elsewhere - see below

It should definitely

> But since it works perfectly ... never change a running system ...

1. Still crashing system (I never got this crash before you gave me the hint to rename BIN into EXE and run it as-is )
2. Bugged VALX

At least, I fixed this bug and many other bugs in DPMIST32.BIN, and also did a few other improvements:
