For many years, that was true for Fortran.  Maybe it still is.

For one, C allowed either of two possibilities when dividing
with negative numbers. Fortran allowed only one.

If any hardware generated the result that Fortran didn't allow,
it would have been less efficient for Fortran, and might not
have sold as well.

Also, my always favorite example is segment selector zero for protected
mode on the 80286 and later intel processors.
