mwArrays causing a compiler error using C++ builder (but only with a 64 bit target platform)

Hi all,

I'm having an issue trying to use mwArrays (2013B) with C++ builder (Rad Studio Xe7). The following code snippet:

mwArray  matlab_matrix(3,3,mxDOUBLE_CLASS);
double   value = matlab_matrix(1,1);

compiles with a 32 bit compilation target, but causes an "internal compiler error" with a 64 bit compilation target. I'm pretty sure I'll need the 64 bit target to link against Matlab's 64 bit dlls.

Its safe to say I'm way out of my depth on howt this happens, so any comments, causes, idea, or workarounds would be much appreciated,

Cheers,

Andrew
