            Bug ID: 82718
           Summary: Bad DWARF5 .debug_loclists generation
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

Created attachment 42470
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42470&action=edit
reduced code example from elfutils libelf/elf_begin.c

Given the attached e.c building wth -O2 -gdwarf-5 produces a .debug_loclists
that the assembler cannot process:

$ gcc --verbose-asm -dA --save-temps -g -O2 -gdwarf-5 -c e.c
