Re: [TUHS] C++ / Kernel

That's a different issue (as I alluded to in my post). Alignment on machines is a different problem. Type "punning" isn't the problem, the compiler is propely converting one pointer type to another but the operand is not correctly aligned. In the case I'm referring to, the Univac and the HEP encode partial word sizes in the pointer. If you take the literal bits from one pointer to another (as if you stored it in a union), then you end up referring to the wrong sized operand in the subsequent operation. Had you converted it to void* or explicitly forced a conversion wih the cast, the compiler would have taken care of converting the pointer for you. It's very odd when you find the machine storing the WRONG SIZE operand from the pointer type in use. As I said, it wasn't hard to fix (just grep for all the afflicted unions), but it took a bit of long kernel debug sessions to figure out what was happening.
