NAG f95 agrees with this and prints at run time:
Rank 1 of array operand has extent 7 instead of 20
In UPPER, line 9 of test.f90

I think the rank is not a problem as MERGE is an ELEMENTAL function and a
scalar ("string") is conformable with any array (such as "tmp"). However, there
is the problem that the string length is not the same (1 and 7); NAG f95 prints
at run time:
Differing character lengths (1 and 7) in MERGE
In UPPER, line 10 of test.f90
