Comment (by kelman):

 Where did you get gfortran from, and what version is it? Amazingly,
 Mathworks still recommends Gfortran 4.3
 http://www.mathworks.com/support/compilers/R2013b/index.html?sec=maci64
 which is getting rather old now.

 How large are your problems that are causing the downloaded mex file to
 crash? There were some memory allocation bugs in the Matlab interface on
 large problems that we fixed, but I can't recall whether those fixes were
 before or after the posted mex file was compiled. There were also some
 exception handling issues due to the compilers and static linking I used
 at the time.

 I'm guessing you updated both your OS and Matlab installations since you
 compiled the previous mex file "one year ago or so," so it doesn't
 surprise me at all that Matlab is crashing with it.

 I just went through my email and found the last conversation I had about
 the OS X exception handling issues and the special compilation approach I
 used to get around it:

   OSX was a little tricky because I needed to mix compilers, statically
 linking to gfortran libraries from the GNU installation, but dynamically
 linking to C++ from Xcode, and using the framework vecLib versions of Blas
 and Lapack.

   So first I created the build directory with a share subdirectory, and
 copied Ipopt/contrib/MatlabInterface/MatlabInterface.site to
 build/share/config.site.

   I ran configure as

   ../configure --enable-matlab-ma57 CC=gcc --enable-matlab-static \
     --with-blas='-framework vecLib' --with-lapack='-framework vecLib'

   Then in build/Ipopt/contrib/MatlabInterface/src/Makefile, on the LDFLAGS
 line, comment out
     -static-libgcc -static-libstdc++
   On LIBS = <...> line, delete -lgcc_eh and
     -L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin11/4.6.2/../../..
