I kind of lost track of them at some point but the following issues can = no longer be triggered: fuzz-libdwfl-crashes/oss-fuzz-45629 \ fuzz-libdwfl-crashes/oss-fuzz-45634 \ fuzz-libdwfl-crashes/oss-fuzz-45635 \ fuzz-libdwfl-crashes/oss-fuzz-45636 \ fuzz-libdwfl-crashes/oss-fuzz-45646 \ fuzz-libelf-crashes/oss-fuzz-45637 \ fuzz-libelf-crashes/oss-fuzz-45682 The unit tests have nothing to do with the fuzz branch because once I = pointed the tests to the master branch they also failed. Looking at "phdr[8]: unknown object file note type 3405650558 = with owner name 'FDO' at offset 200" it seems it's caused by the toolchain used there. On Fedora 35 the tests pass.
