Make crashes when -r and MAKEFLAGS= are specified on the command line. On startup make begins to process command line arguments. During processing of "MAKEFLAGS=" make calls reset_makeflags, which in turn calls disable_builtins, which dereferences null suffix_file. Here is the backtrace. 0 disable_builtins main.c:3482 1 reset_makeflags main.c:3104 2 set_special_var variable.c:1325 3 do_variable_definition variable.c:1693 4 try_variable_definition variable.c:1889 5 handle_non_switch_argument main.c:3021 6 decode_switches main.c:3150 7 main main.c:1621 * src/main.c (disable_builtins): Avoid dereferencing null suffix_file. * tests/scripts/features/suffixrules: Add a test.
