            Bug ID: 89514
           Summary: -g -fdebug-types-section -flto gives 'Dwarf Error: bad
                    length' in gdb
           Product: gcc
           Version: 8.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gcc at mailinator dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

#include <iostream>
int main() 
{
    std::cout << "Hello, World!";
    return 0;
}

g++ hello_world.cc -g -fdebug-types-section -flto -o hello_world
gdb hello_world

Then GDB 7.11.1, 8.1, 8.2 reports: 
Dwarf Error: bad length (0xe7) in compilation unit header (offset 0x1e3a + 0)

For larger binaries GDB reports a corrupted dwarf version:
Dwarf Error: wrong version in compilation unit header (is 3745, should be 2, 3,
or 4)

Reproduced on GCC 8.1, 8.2, 8.3 with Binutils 2.30 and Binutils 2.32.

At first I suspected Binutils, then GDB, but I think this is a GCC issue, since
-fdebug-types-section works with -fwhole-program, but not -flto.
