Hi,
When we run ftpd in debug mode (option --debug on the command line), the
server crashes upon incoming connections. The bug comes from the
functions reply() and lreply() in the file ftpd/ftpd.c: The functions do
not "reset" the "va_list" before calling syslog(). So, the latter gets
the end of the list of arguments. This triggers a crash on my PowerPc
based target !
Please apply the following patch:
