I still see it with version 4.2.0 20060222 :(

For me, on Linux/x86, it works with revision 111200, but ICEs with 111300 and
111387.

A few binary search steps later: Works with revision 111270, fails with 111271.
 It seems to be related to the patch

2006-02-19  H.J. Lu  <hongjiu.lu@intel.com>

        * resolve.c (resolve_contained_functions): Call resolve_entries
        first.
        (resolve_types): Remove calls to resolve_entries and
        resolve_contained_functions.
        (gfc_resolve): Call resolve_contained_functions.

First, I am sorry to be a "doubting Thomas" - I finally succeeded in
reproducing the problem.

Second, I unpatched the above and find that this is indeed the problem.  I will
try to understand why but I will (i) Post this to the list and (ii) remove it
from mainline tonight.
