Is this a bug in CWSDPMI?* If it's not FAQified yet - the "Page fault at ..." is an important confirmation that it's a pointer problem. That means you referenced a memory location which is protected or undefined. Null pointers will always be page faults. > under QDPMI you will crash (the well-known QDPMI bug in handling Int 24h). Under SOME releases of QDPMI. The version I have handles int 24h correctly (it's an older release). It seems they broke Int 24h in the later releases.
