The r13-r2000 object map scanning has been fixed for a while.

Also r2004-r2018 mostly works now, just some handles are not resolved because not all objects/classes can be fully read yet, and thus those handles go missing.

2007 is now also fixed, will work on the 2010 and 2013 versions now. looking good.

The problem is not the object map scanning, only minor parts in some object are still buggy.

Thanks for the files.
With the R13-2004 versions all objects can now be successfully read.

For 2007 only partially until I can fix the remaining string and handle stream offset bugs.

2010 and 2013 crash on the BLOCK_CONTROL with an invalid bitsize. This should be fixed soon.

The problem appeared only for versions R13, R14 and R2000. For R2004, the object map and data are correct, each one in its own section.

The OBJECT MAP scanning specification from ODA seems to be broken, I have tested extensely and didn't figure out a way to accomplish the task in every situation.

This link has files where we can prove that Libredwg is not able to scan all objects present in a DWG file: https://sites.google.com/site/fefcas/dwg

I have seen errors in the code, but even fixing them, problems get even worse, because the DWG object map section seens to be very buggy.

The way to go, I think, is bypass the object map section, and try to scan them directly.
