While multiple hardlinks of binary located in different dirs, there are also multiple hardlinks of separated debug info file with the same binary name in same debug dirs. But in each dir, only one debug file with original name works. Because all of binary hardlinks have one `.gnu_debuglink' which is added in `splitdebuginfo'. It caused gdb could not find debugging symbols. [Before the patch] $ find . ./usr/bin/foo ./usr/bin/foo-hd1 ./usr/bin/.debug ./usr/bin/.debug/foo ./usr/bin/.debug/foo-hd1 ./usr/libexec/foo-hd2 ./usr/libexec/.debug ./usr/libexec/.debug/foo-hd2 $ readelf --debug-dump usr/libexec/foo-hd2 Contents of the .gnu_debuglink section: Separate debug info file: foo $ gdb usr/libexec/foo-hd2 Reading symbols from usr/libexec/foo-hd2...(no debugging symbols found)...done.
