check bp setting on exec #130

Closed stsp closed 4 years ago

https://github.com/stsp/fdpp/blob/master/kernel/procsupt.asm#L70 This claims that the bp value "is more or less random", which doesn't sound plausible, and is not so according to dr-dos sources. Needs to set bp the way dr-dos does.

Hmm, bp seems to point to the caller's registers, but as long as the segment of the caller stack is unavailable in any register, it is probably fine to treat bp value as random...
