1. Use GDC or DMD-1.028. Currently DMD specific DWARF extensions not supported.

2. Try patch binary before debug it.

For example we have binary crash_test. 
With next command we can see if DW_TAG_module have "has children" flag:
objdump -W crash_test 2>/dev/null | grep DW_TAG_module

 <1><138>: Abbrev Number: 2 (DW_TAG_module)
   2      DW_TAG_module    [has children]

Try patch it:
sed "s/\x1e\x01\x03\x08/\x1e\x00\x03\x08/" -i crash_test

And see again what we have:
objdump -W crash_test 2>/dev/null | grep DW_TAG_module

 <1><138>: Abbrev Number: 2 (DW_TAG_module)
   2      DW_TAG_module    [no children]
