I'm using elfutils-0.158-1.fc20.x86_64, but I don't think git libdwfl has changed in any relevant way since then. The gist is that I have an ET_EXEC binary, /usr/bin/ls. When I call dwfl_module_getsymtab -> find_symtab -> find_aux_sym -> open_elf, the following heuristic is triggered: libdwfl/dwfl_module_getdwarf.c 134│ mod->e_type = ehdr->e_type; 135│ 136│ /* Relocatable Linux kernels are ET_EXEC but act like ET_DYN. */ 137│ if (mod->e_type == ET_EXEC && file->vaddr != mod->low_addr) 138├> mod->e_type = ET_DYN; Here file->vaddr = 0x400020 and mod->low_addr = 0x400000, but this certainly is not a kernel, and should not be treated as ET_DYN. Maybe this only needs to add a check that file == &mod->main, but I wonder if this heuristic is even needed at all, because report_kernel() forcibly sets ET_DYN itself. Thoughts? Josh
