This problem should be fixed by this change:

You can reproduce the problem with the example file from Octave.
A warning occurs during compilation:

octave/examples> mkoctfile --mex myfeval.c
myfeval.c: In function ‘mexFunction’:
myfeval.c:21:3: warning: passing argument 4 of ‘mexCallMATLAB’ from incompatible pointer type
octave/mexproto.h:77:26: note: expected ‘mxArray **’ but argument is of type ‘const mxArray **’

and the execution of the MEX file returns an error:

octave:1> myfeval
error: octave/examples/myfeval.mex: failed to load: octave/examples/myfeval.mex: undefined symbol: mexCallMATLAB

There seems to have been a change over the last days such that MEX files calling mexCallMATLAB now crash:

failed to load: file.mex: undefined symbol: mexCallMATLAB
