Diagnostic feedback when disassembly fails is needed

After a lot of blindly stumbling around in the dark I got DisassemblyDiagnoser to work for a benchmark I'm iterating on, and then a random change to the code being measured made it suddenly stop disassembling all my benchmarks. The only information or diagnostic output I get is:

No benchmarks were disassembled

It would be awesome if there was some way to get diagnostic information here. Like did decoding the pdb fail? Did nothing get jitted during benchmark execution? etc.
