If the MIDAS Alarm property "write elog message" is enabled, an uninitialized variable "tag" is passed to 
el_submit() and depending on your luck, cause a crash. "tag" is supposed to be and is now a NUL-
terminated string. The only other use of el_submit() is in mhttpd.cxx and mserver.c, where it is called 
correctly.
