ivlpp: Fix segfault in macro_start_args macro_start_args truncates def_buf, but does not check to ensure that someone has allocated def_buf first. This will cause a null pointer dereference if the first access to def_buf while parsing a file is a macro invocation. Fix this by avoiding truncating def_buf if it is NULL, as it is effectively already truncated. Fixes: 680196953 ("Add support for text macros with arguments.")
