[asterisk-users] ast_dynamic_str_thread_build_va() is defined with 6 args but only called with 5 args??

[Frank Tarczynski]

I'm having a problem with asterisk-1.4.4 dumping core under Solaris 10 
with a SIGSEGV error.

gdb gives this stack trace:

#0  0xfebd4d0c in strlen () from /usr/lib/libc.so.1

I've noticed that ast_dynamic_str_thread_build_va is defined in utils.c 
on line 969:

int ast_dynamic_str_thread_build_va(struct ast_dynamic_str **buf, size_t 
max_len,  struct ast_threadstorage *ts, int append, const char *fmt, 
va_list ap)

and it's called in cli.c on line 69:

res = ast_dynamic_str_thread_set_va(&buf, 0, &ast_cli_buf, fmt, ap);

Most interesting is that the function is defined with 6 arguments and 
only appears to be called with 5(?).  Is this correct?
