With up to date trunk (GNU Fortran (GCC) 8.0.0 20171109),
I see
% gfcx -c a.f90
a.f90:3:31:
character :: c(1) = [t()]
1
Error: Derived type 't' at (1) is being used before it is defined
I see the same error for the code in comment #2. I'll prepare
testcases and commit those later today or tomorrow.
