I compiled the magic square example in the documentation using MCC. When I run the standalone executable at the system prompt, I get the following error:

 *** glibc detected *** free(): invalid pointer: 0x080a5ca0 ***
 *** glibc detected *** free(): invalid pointer: 0x080a5b40 ***
 *** glibc detected *** free(): invalid pointer: 0x080a5b58 ***
 *** glibc detected *** free(): invalid next size (fast): 0x080a5a28 ***
 *** glibc detected *** malloc(): memory corruption: 0x080a5a50 ***
 Segmentation fault

This error occurs when the version of the GCC compiler that is used is not compatible with MATLAB Compiler 4.4 (R2006a). The following page contains a list of compilers compatible with different versions of MATLAB:

The appropriate GCC version can be downloaded from the following website:
