Version and Platform (required):

Bug Description: Unable to load PDB when executable is not compiled with /debug flags, or when GUID does not match between the PDB and .exe file.

Steps To Reproduce:

1. Load an .exe file not compiled with /debug
2. Tools > Plugins > PDB > Load PDB is greyed out

Additional Information: There was discussion on Slack on this topic and the consensus was to have this allowed and display a warning for the user.

Thanks for the issue. I know this request has come up before but I don't see it as currently tracked. This should be resolved for the next stable release.

This is resolved as of 3.1.3718-dev. The automatic PDB loader will check for matching guid + info in the exe, but if you manually choose to load a PDB it will warn you and allow you to load it anyway.
