OpenMP incompatible with LAPACK & BLAS routines

I've written a few c mex files and have called dsyev to find eigenvalues etc. I want to call this routine in parallel in a threaded loop. Everything compiles OK without warnings (using MS Visual Studio Prof. Edition 2005).
However, when I call it from Matlab it just crashes, without any error messages...
Anyone have any ideas?!?
Thanks in advance
Adam

@zhuanyi Can you open a new Question, and maybe include a minimal complete example that reproduces the problem?

Running your original mex function within a MATLAB Parallel Computing Toolbox parfor loop might give you the parallelism you want.
