In DWARF2-DWARF5 if the code reading an object finds a FORM that is
unknown it's impossible for the reader to ignore this.
The object file DWARF really does become unreadable.
You don't make clear what tool you are using to read DWARF.
Nor what tool created the DWARF information.
Nor does your quoted text above seem to be a copy-paste
of the actual error text.
If you could supply a little more information perhaps
someone could help.
Tools that can help diagnose this are:
readelf (GNU binutils)
dwarfdump (git clone https://github.com/davea42/libdwarf-code)

IANAL, but I watch actors play lawyers on high-definition television.
