Nice. I faintly remember testing using the PDB files with WinDbg at some 
point (not with minidumps though, only with intercepting a live crash), 
and I think that should work, as should using the full Visual Studio IDE. 
I haven't tested that setup lately though.

If you're using lldb in the end, there shouldn't be much need for actually 
using PDBs, as lldb should be able to use minidumps together with the 
default DWARF debug info as well.
