# 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 max_range = 42;
#
# int main (int argc, char **argv)
# {
# char chars[max_range];
# chars[max_range -1] = 7;
# return 0;
# }
#
# This would crash the low-level check_debug_info in the past.
