Possible patch for 62242

[Louis Krupp]

As far as I can tell, the problem in 62242 (and possibly 62246) is with a 
string array constructor trying to deal with an array element whose value is a 
character function that is described in an interface block and which has an 
assumed-length result.  I can't claim more than a superficial understanding of 
the code, but this patch seems to work.  I ran make check-fortran, and I saw no 
regressions.
