This is still being discussed upstream:

But I think the consensus is that it is a packaging bug.
It means that although you package contains native binaries there is no
correct DWARF produced so no corresponding source files have been found.
This is usually caused by a missing -g in the build flags or the native
compiler (fpc in your case I assume) not producing correct DWARF
debugging information.

That is definitely a bug in your package or the fpc compiler.
Stabs is a ancient debuginfo format that isn't supported by any/most
modern tools. You should definitely see if you can figure out how that
happened and how you can produce normal DWARF debuginfo.

I am not sure exactly how this happened. It happens when handling a
Dwarf DW_FORM_ref_addr construct. You might have to report a bug report
against dwz with the files so we can track this down.

But note that this doesn't abort the build (maybe it should, but it
currently doesn't - it just means your DWARF debuginfo won't be

The reason your build failed is the first issue of missing/incorrect
DWARF generation so that no source files could be found.
