--- Comment #1 from Lynda Rowe <lynda.rowe at ericsson dot com> ---
If I was to build the same mixed dwarf4/5 source example with gcc v. 14.2.0 and
ld 2.43 as I used to build readelf like this:
rm -f dwarf4.o dwarf5.o && gcc -c -g -O1 -gdwarf-4 -o dwarf4.o dwarf4.c && gcc
-c -g -O1 -gdwarf-5 -o dwarf5.o dwarf5.c && gcc dwarf4.o dwarf5.o -o a.out
I get sligthly different output for .debug_loc but the same behaviour for the
.debug_loclists section and similarly odd looking header information:
$ ../build2/x86/binutils/readelf -W -wo a.out
Contents of the .debug_loc section:
