For example, if your name.c code is using int for array sizes instead of mwSize, mwSignedIndex, etc. etc. then the code will not work if any of those are passed by reference to a function (i.e., passing an address of an int to a routine that is expecting the address of an 8-byte unsigned integer for a size will obviously not work). The function would get garbage when it dereferenced the pointer, and if subsequently used as an agument for a memory allocation I could see how you might get an "out of memory" error.

Hi, I have exactly the same problem as you mention. First, I add '-largeArrayDims' option but it caused another problem saying that out of memory. How can I fix this problem? Do you think it is because of matlab version? I really need help please.
