... got continual 0xC0000005 (memory access violation) exceptions

You're using gcc-4.x.x ? Try adding -Wl,--enable-runtime-pseudo-reloc-v2 to the g++ command line during the build process. That should fix the problem, I believe.
It's a known libstdc++ issue, so you may find that installing a gcc that has been built from a more recent source also takes care of it (without any need to add anything to the g++ command line).

Cheers,
