... and regtests cleanly.


Unfortunately, there is one more complication: When compiling the two files
from comment #1 one after the other, one gets a linker error:

> gfortran-4.7 -c module.f90
> gfortran-4.7 program.f90
/tmp/ccU0pMIF.o: In function `MAIN__':
program.f90:(.text+0x16): undefined reference to
`__g_nodes_MOD___vtab_g_nodes_T0'
program.f90:(.text+0x87): undefined reference to
`__g_nodes_MOD___vtab_g_nodes_T1'


Note: This seems to happen with trunk and 4.6, while it works with 4.5. I was
hoping we had gotten rid of those for good (cf. e.g. PR44065 and PR45674).
