$ cat a.d
module a;

import p.b;

void main() {
}

$ cat p/b.d
module p.b;

void moo() {
}

$ dmd a.d p/b.d -c -gc
$ dmd a.o  b.o
$ dwarfdump a > /dev/null
dwarfdump ERROR:  dwarf_offdie:  DW_DLE_DIE_ABBREV_LIST_NULL (151)
$ objdump --dwarf a > /dev/null
objdump: Warning: .debug_info offset of 0x2f in .debug_pubnames section does
not point to a CU header.

Please note: dwarfdump may or may not be buggy by itself, and what objdump
outputs is just a warning. It may be that this is not really an issue.

It's reproducible with dmd 2.042 and phobos, so it's probably an issue with how
the dwarf info is merged between object files.

Curiously, neither dwarfdump nor objdump complain about either a.o or b.o
individually.
