Ah.  Doubtless.

AFAIR the front end is somewhat hamstrung (perhaps depending on
exactly what the issue is) and there have been long-standing problems,
especially with the debugging info generated leading to gdb crashes
trying to assumed-size arrays (which used to appear with huge or
negative dimensions).  There's an essay on this area in f/com.c
(ffecom_sym_transform_), at least I think it's relevant.

I think Fortran isn't really usable until this is resolved somehow
because that construct is very common.  I doubt I can be much help
other than maybe explaining the fortran issues if a wizard is able to
look into it.
