[Frazee, Alexander]

I am new to DMPs and WinDbg. I am getting this same issue (i.e. not in JIT code range, INVALID POINTER, unable to verify checksum, etc). Have analyzed multiple dump files and they all produce the same result. Right now, I believe it to be my PDB Symbol File Path that might be causing the issue.
