# Test anonymous block-data statements.

# A name for BLOCK DATA in Fortran is optional.  BLOCK DATA is used
# for one-time initialization of non-pointer variables in named common
# blocks.  GDB used to crash with 'Intel ifort'-generated code, which
# outputs nameless DW_TAG_module, unlike with gfortran which just
# doesn't emit DW_TAG_module in this case.
