minimized testcase taken from 481.wrf (original was 10k lines, now ~1k)

While building the 481.wrf SPEC CPU2006 benchmark using dragonegg-2.7 (in
combination with gcc-4.5.0), I'm running into the following assertion failure:

gfortran -fplugin=dragonegg.so -c -o module_ra_gfdleta.fppized.o -I.
-I./netcdf/include -O2 module_ra_gfdleta.fppized.f90

f951: /path/to/LLVM/2.7/dragonegg-2.7/llvm-convert.cpp:8559: static
llvm::Constant* TreeConstantToLLVM::ConvertUnionCONSTRUCTOR(tree_node*):
Assertion `(VEC_constructor_elt_base_length(((elt) ? &(elt)->base : 0))) == 1
&& "Union CONSTRUCTOR with multiple elements?"' failed.

I ran into the same problem using llvm-gcc-4.2-2.7: 

gfortran -c -o module_ra_gfdleta.fppized.o -I. -I./netcdf/include -O2
module_ra_gfdleta.fppized.f90

f951: ../../llvm-gcc-4.2-2.7.source/gcc/llvm-convert.cpp:8207: static
llvm::Constant* TreeConstantToLLVM::ConvertUnionCONSTRUCTOR(tree_node*):
Assertion `(VEC_constructor_elt_base_length(((elt) ? &(elt)->base : 0))) == 1
&& "Union CONSTRUCTOR with multiple elements?"' failed.

A minimized testcase which should allow to reproduce is attached.
