--- Comment #6 from Ian Lance Taylor <ian at airs dot com> --- On the other hand the libbacktrace testsuite now fails when using dwz 0.13+20201015-2. But I guess that is not a GCC problem. dwz -m b3test_dwz_common.debug b3test_dwz_1 b3test_dwz_2 dwz: b3test_dwz_1: Unknown DWARF DW_FORM_implicit_const dwz: b3test_dwz_1: Couldn't read abbrev at offset 0x0 dwz: b3test_dwz_2: Unknown DWARF DW_FORM_implicit_const dwz: b3test_dwz_2: Couldn't read abbrev at offset 0x0 dwz: Too few files for multifile optimization make[3]: *** [Makefile:2436: b3test_dwz] Error 1
