Similar reasons as with Matlab.
GAMS brings its own libstdc++ and libgfortran and they are so ancient 
that they don't work with your own Ipopt installation.
I usually move the one from GAMS away, so solvers use the libs that come 
with the system again. So far, that worked without problems for me.
