Not really. The program receives a SIGSEGV in ndo_escape_buffer because it gets
passed an invalid pointer (memory address 0x44 is not available to programs).

Why it gets passed a bogus address on Solaris is a mystery to me, as
contact_struct->name is located at relative address 0 within the contact_struct
data structure (unless your compiler re-arranges it ofcourse).
