[Patch, fortran] PR58771 - [4.7/4.8/4.9 Regression] ICE in transfer_expr, at fortran/trans-io.c:2164

[Paul Richard Thomas]

Dear All,

When I first posted it in Bugzilla, I thought that this patch is too
kludgey by far.  However, it has grown on me and I now think that it
is the right thing to do.  The patch is self-explanatory.

Bootstrapped and regtested on FC17/x86_64 - OK for trunk and 4.7/4.8
with an appropriate delay?

Cheers

Paul
