The DWARF Debugging Standard Committee (http://dwarfstd.org) is planning to resume meetings starting in February. The DWARF debugging file format, as you likely know, is widely used by compilers and debuggers to support source level debugging. The Committee released Version 5 of the DWARF Standard in 2017 and will start work on Version 6.
The committee consists of more than 20 committee members from a broad cross-section of the compiler and debugger development community, representing a dozen companies and including a number of independent developers, working on both proprietary and open source products.
A list of the current proposals or issues can be found on the Open Issues web page: http://dwarfstd.org/Issues.php. If you would like to submit a comment, proposal, or issue, go to the Public Comment page: http://dwarfstd.org/Comment.php.
