Has anything changed with lineinfo for dwarf 4?  (Actually I am not sure if it worked before, but I am unaware of problems before) I updated to latest svn yesterday. So more or less up to date.

fpc.exe -B -MObjFPC   -gw4  -O-  -WG   ArgVPrg.pas

the "objdump" from trunk/install/binw64/objdump.exe  can not correctly read it, lines and addresses are there, but filenames/dir are empty. gdb has issues too.
