           Version: 4.6.2
            Status: UNCONFIRMED

Program causing the ICE

The attached program causes an ICE in gfc_get_derived_type, at
fortran/trans-types.c:2401, both in version 4.6.2 and 4.7.0 20111212 (a very
recent nightly build). The reported location is the same.

It may be related to other reported bugs vis-a-vis gfc_get_derived_type, but
as far as I can tell, they concern a different location in the source file.

The report is:
