The code dies before entering main(). The _start() function is the entry
point of the executable, it arranges for loading of dynamic libraries
and initialization of the C runtime. THe _init() function initializes
the state of one of the shared libraries and is called as the library
is loaded. When smtp(8) dies this early, there is something quite wrong
with your build or run-time environment.
Try building without PCRE and SASL, if that fixes it, figure out what's
wrong with the SASL and PCRE libraries. If the executable still crashes,
try Sun's compilers. Perhaps your GCC install is not quite robust.
