            Bug ID: 27371
           Summary: [readelf] .debug_rnglists section header not parsed
           Product: binutils
           Version: 2.37 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

...
$ g++ gdb/testsuite/gdb.cp/cpexprs.cc -gdwarf-5 -fdebug-types-section
$ ~/binutils/install/bin/readelf -w a.out     
Contents of the .debug_rnglists section:

    Offset   Begin    End
    00000000 readelf: Error: Invalid range list entry type 126
    0000000c 00000000004008c8 00000000004013f1
    00000017 00000000004013f2 0000000000401407
...

Looking with llvm-dwarfdump:
...
.debug_rnglists contents:
range list header: length = 0x0000047e, version = 0x0005, addr_size = 0x08,
seg_size = 0x00, offset_entry_count = 0x00000000
ranges:
[0x00000000004008c8, 0x00000000004013f1)
[0x00000000004013f2, 0x0000000000401407)
...

The entry type 126 is 0x7e in hex (which occurs in the length field of the
header).  Looks like the section header is not parsed.
