We have a clarification from Apple on the problem of
dsymutils asserting since the VTA merge changes...

Does the code in gcc/dwarfout.c currently check if
any block form with zero length actually has a
valid location before actually emitting a DW_AT_location attribute?
Apple believes that these shouldn't be emitted in that case.
This issue is currently preventing darwin from emitting
dwarf debug information (dSYM) in parts of gcc trunk (PR41473).
Thanks in advance for any information on this issue.
