move(trip, _minmax[1].fasts[1].fast_trip, sizeof(fastid));

where fastid has a size of 4.

The compiler emits a "mov ax, 4" twice.

Absolutely no clue why. Use 4 (and loose portability) and it's OK.

Having fun decompiling code to mis-matched source, and given that all the 
Borland Pascal compilers are simple one-pass programs, that turns out to 
relatively easy! ;)

PS: And no I haven't got anything better to do.
