If I understand you correctly: we don't yet know exactly what was going wrong on my machine when I tried to set the conditional break point, so we lack a concrete case in which --enable-check-lisp-object-type affected debugging with GDB, and we are thus not in a position to assert in etc/DEBUG that --enable-check-lisp-object-type has the potential to have an effect on debugging with gdb? When you wrote that comparisons with structs are not guaranteed to work with gdb, you were /not/ going as far as saying that comparisons with structs are never expected to work (because that would imply that --enable-check-lisp-object-type would often lead to issues when debugging)? If this summary is right, I think this bug should be closed. Thanks. -- Sean Whitton
