Collateral exceptions seem to be broken

[Andrej Mitrovic]

You mean my build of DMD/Phobos?

Well the debug symbols are definitely shown after I run cv2pdb on the
executable (it makes a .pdb file with all the symbols which get loaded
at runtime by the exe).

Perhaps displaying names is just unimplemented yet in 2.053 for
Windows. Using cv2pdb is not a problem for me (and it allows me to use
VisualD's debugger, which is nice).
