Gerhard, I don't know if you like to keep track of issues
that you submit or not.  The above is quite strange if 
integer(8) is replaced with integer or integer(4),  I get
the expected error message.  If it is integer(1), integer(2),
or integer(8), it silently compiles.  If I do, 

print *, [integer(8) :: 2, '3']

I et the expected error.  Do you want to migrate this to its
own PR?  If not, I'll do it when I get around to committing the
fix for the other issues.
