If it is crashing very early, run ldd on the executable and checked to
see if it is linked to both libstdc++ and libc++.  My experience is that
it is a fatal combination.  This happens if it is using some libraries
containing c++ code compiled with g++, and other libraries containing
c++ code compilied with clang++, or all of the libraries compiled with
one compiler and the application compiled with the other.  All of the
c++ code needs to use the same toolchain, which can be a PITA to
untangle, since changing the toolchain for one port can break other
ports that depend on it.

For the latter, put WITH_DEBUG=yes in make.conf.  It changes
${STRIP_CMD} from /usr/bin/strip to /bin/true.  For ports that set
INSTALL_TARGET to install-strip, it changes the target to install.  It
also sets DEBUG_CFLAGS to -g.

For the first issue you might try setting DEBUG_CFLAGS to -O0 -g and not
directly setting CFLAGS and CXXFLAGS.
