10 years ago In OSX 10.9.3, with Matlab R2013b, I had the same issue. I was able to solve it as follows:
(1) Install Xcode 5.1 (2) Install command line dev tools for mavericks (march 2014) (3) edit the mexopts.sh file in Matlabroot and modify the maci64 section as shown at the end of this post (4) run mex -setup

MakeMultichannelEXR used to build find under OS X 10.7 and 10.8. The build succeeds in OS X 10.9, but the resulting mex-function is broken, causing a segmentation fault.
This may be related to recent changes in OS X 10.9 and XCode 5. Apple has moved away from gcc for building C and C++ programs, and now favors llvm. It may take time for Matlab to issue patches for previous Matlab versions.
This Matlab issue may be related, although the reported symptoms are different: http://www.mathworks.com/matlabcentral/answers/103904-can-i-use-xcode-5-as-my-c-or-c-compiler-in-matlab-8-1-r2013a-or-matlab-8-2-r2013b
System details where the broken build occurred:
