Hi, Yesterday, I was looking into Firefox Bug 1612422 which aims to create a reproducible build job for mingw, and I came across the following two tools for parsing PDBs, you might find them useful: - microsoft's cvdump.exe: https://github.com/Microsoft/microsoft-pdb/ - LLVM's llvm-pdbutil: https://llvm.org/docs/CommandGuide/llvm-pdbutil.html Best, Sanketh
