The gfortran.dg/g77/980628-3.f testcase fails the execution test when compiled with llvm-gfortran.

...since commenting them eliminates the execution failures. Note that this test case concerns...

• g77 0.5.23 and previous had bugs involving too little space
• allocated for EQUIVALENCE and COMMON areas needing initial
• padding to meet alignment requirements of the system.

The original testcase is attached.

This now crashes the compiler with:

f951: ../../gcc-4.2.llvm/gcc/llvm-types.cpp:2147: const llvm::Type* TypeConverter::ConvertRECORD(tree_node*, tree_node*): Assertion `(isBitfield(Field) || FieldNo == ~0U || FieldOffsetInBits == 8*Info->ElementOffsetInBytes[FieldNo]) && "Wrong LLVM field offset!"' failed.
