c-tests.el test failure in 21.5

Greetings - In a current 21.5 -debug build, I'm seeing the following failure when running the c-tests.el test from the test suite: Testing /usr/local/src/xemacs-21.5-2005-11-30-debug/tests/automated/c-tests.el... Fatal error: assertion failed, file /usr/local/src/xemacs-21.5-2005-11-30-debug/src/tests.c, line 365, !memcmp (BYTE_BUF_BYTE_ADDRESS (current_buffer, charbpos_to_bytebpos (current_buffer, ((current_buffer)->bufpt + 0))), int_foo, sizeof (int_foo) - 1) make[1]: *** [check] Aborted (core dumped) make[1]: Leaving directory `/usr/local/build/xemacs-21.5-2005-11-30-debug/src' make: *** [check] Error 2 (All the other tests pass, by the way.)
