diffoscope will try to locate a package with matching debug symbols when it's comparing ELF files inside two .deb. It will indeed look at the files in the parent container (in your case a directory), but it's only a quick look: looking for .deb files and looking at the control file. Still, it was indeed looking at all files in the tree. Could you try the attached patch and see if it helps? -- Lunar .''`. lu...@debian.org : :Ⓐ : # apt-get install anarchism `. `'` `-

Otherwise, we would be looking at all files in the tree instead of just the one at the same level as the binary package.
