Take this with a huge grain of salt since I'm a novice at gdb...  It
seems like something is corrupting arguments passed from line 593 in
comm.c to network_printf in nessus-core/nesssu/auth.c.  [Notice that
data is a null pointer?] 

What sort of args / optimizations did you use when compiling Nessus?
Does it help to omit optimizations?

mtrace comes from libc, I believe; "man mtrace" should tell you more.
