Looks like a clash between the two compilers. For some reason your
compiler in /usr/local/gcc-3.4.4 is finding and linking against the cygwin
compiler's libstdc in /usr/lib/gcc/.
Googling for '__w32_sharedptr_terminate throws up....
http://gcc.gnu.org/ml/gcc/2004-04/msg00636.html
which is an inconclusive thread but may perhaps throw some light on the
problem
