I have verified it for DWARF (GDB no longer supports version 1 and any version 2
upwards behaves the same in this simple case). I do not know if it works for
STABS and other formats but any non-DWARF format has poor debugging anyway and
there is normally no reason to use anything else than DWARF.

We can conclude then it may be a workaround of GDB bugs in non-DWARF formats
support (maybe, maybe not). I do not find meaningful to actively support
non-DWARF debugging, it is just best-effort.
