It's weird. I have applied your patch and rebuilt but I still get the double
error, and the segfault:

pr31251.f90:1.16:

  character(len=2.3) :: s
               1
Error: Expression at (1) must be of INTEGER type
pr31251.f90:1.16:

  character(len=2.3) :: s
               1
Error: Expression at (1) must be of INTEGER type
==3668== 
==3668== Invalid read of size 4

==3668==  Address 0x2 is not stack'd, malloc'd or (recently) free'd
pr31251.f90:0: internal compiler error: Segmentation fault


I don't know what the heck is happening here, but I'll try to understand it
better in the next few days.
