Good thing I said "seems to be."

I was 100% wrong on this, it was not the compiler at all but the programmers.

ReadFile() takes a pointer to a 32-bit value to return actual count of
bytes read.  In the code clean up / move to 64-bit / conversion to the
new API, the variable was changed to a size_t.  In ReadFile() the
variable was cast as a pointer to a 32-bit variable.

Well, that's no good on 64-bit Windows. <grin>

Anyhow, sorry I blamed the compiler, it wasn't a compiler bug at all.
