# CHECK-NEXT: error: .apple_names Bucket[1] Hash[1] = 0x0002b60f Str[0] = 0x0000005a DIE[0] = 0x00000001 is not a valid DIE offset for "j".
# This test is meant to verify that the -verify option
# in llvm-dwarfdump, correctly identifies
# an invalid hash index for bucket[0] in the .apple_names section,
# an invalid HashData offset for Hash[0], as well as
# an invalid DIE offset in the .debug_info section.
# We're reading an invalid DIE due to the incorrect interpretation of DW_FORM for the DIE.
# Instead of DW_FORM_data4 the Atom[0].form is: DW_FORM_flag_present.
