Hi,

I’m tracking down a nasty crash, game quits to desktop with the error “pure virtual function call”. I have a dmp file and tracked it to fmod, but I can’t seem to find the pdbs for PC in the installer- are these available anywhere?

Thanks

We can supply the pdb’s as required, what version of FMOD for Unity are you using?

We are using 2.00.03. The crash I get is in the “L” logging dll, but both would probably be useful. Thank you!
