annotate src/debug.c @ 4974:fe0d3106cc36
fix compile problems in bytecode.c when no error-check-byte-code (issue 666)
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-05 Ben Wing <ben@xemacs.org>
* bytecode.c (bytecode_assert):
Use 0 instead of x in disabled_assert calls to avoid errors due
to using undefined vars/params (they are defined only when
ERROR_CHECK_BYTE_CODE, which also turns on/off the asserts).
