# Following program compiled with "default" gcc settings,
# which is dwarf-2 + gnu extensions. Which will result in:

#  [    a2]      subrange_type
#                type                 (ref4) [    ac]
#                upper_bound          (block1)
#                [   0] fbreg -24
#                [   2] deref
#
# According to dwarf-2 DW_AT_upperbound cannot be encoded with block form.
# It can however with later versions of dwarf, which gcc will output as
# gnu extension (unless -gstrict-dwarf is given).

# int main (int argc, char **argv)

#   chars[max_range -1] = 7;

# This would crash the low-level check_debug_info in the past.
