It is taking me a long time to reduce and still keep the error
Which has different

Hello Richard
My archive of the original problem didn't show it. But when I tried to
re-create I got the following. I'll try also make a small test case for this
one while I have it.

Hi Richard
I have a smaller test case which. It shows only part of the error.
"Dwarf Error: Invalid abstract instance DIE ref"
Richard, would this be useful?

Richard,
Ok I will have a look at that soon...
Could I ask, do you know if GCC already has dwarf sanity checks when outputting
.debug_str size to check offsets are not larger than the size?

It's commercial source code that can't be disclosed.
Is there another way to create a test case which has the same issue? a lot of
debug information?

Perhaps G++ can check those dwarf offsets are within bounds when writing out
the object files itself when saving obj files? Could output a useful warning,
when detected as an internal compiler error.
