Unfortunately I can't compile the examples. I'm not very
familiar with C++ and the cryptic error messages I get about
"undefined" references surely result from some wrong shared
lib setups here.
Anyway - the above tells that something corrupted the stack
and that the core is mostly useless (except for including it
into replies to spam mail).
The destructor eventually calls PQuntrace(), PQclear() and
PQfinish(). Try setting breakpoints on them and then single
step until shit happens.
