I'd tweak this so that you can see all observations in any group that is problematic.
The logic is laid out in the FAQ I previously referred to in this thread.
bysort g1 (g2): generate byte same1 = g2[_N] == g2[1]
bysort g2 (g1): generate byte same2 = g1[_N] == g1[1]
tab1 same1 same2
list if !same1 | !same2

I see. A combination of C�lio's and my ideas comes here:
bysort g1: generate same1 = (g2[_n]==g2[1])
bysort g2: generate same2 = (g1[_n]==g1[1])
tab1 same1 same2
list if same1==0 | same2==0

Svend's idea will not work at all, as my two identifiers
are not meant to take the same values. That is, g1 will
likely never equal g2.
C�lio's suggestion does get at what I want, especially as
it found no errors. However, I'm curious if there is a way
that would also let me identify which records or values
produced the errors; -assert- is uninformative in that
respect.
