address_map return with Err AddressMapNotFound

[wyxloading]

I am encounter some pdb with no omap info ( also none DBIExtraStreams.section_headers ).
When i call pdb.address_map() and Err(AddressMapNotFound) returned.
I wonder if this behavior is expected?
I am trying to dump the symbol tables, using the address_map to translate (metioned in #17 )
What should i do with pdbs without extra streams or omap infos?

Here is the sample pdb i download from microsoft symbol server.
mscorlib.ni.pdb.zip

Without section headers, the PDB can't translate {section, offsets} to/from RVAs. There's simply no data for a pdb::AddressMap to use.

You could perform such translation yourself using the section headers in the corresponding executable, but pdb doesn't touch executables, so that's out of scope here.
