Crash in dgesv, MKL 10.0.1 on MS Windows

Hello,

We've recently upgraded to MKL 10 and found that dgesv is crashing on the most simple cases. The kernel being used is p4m.We are linking dynamically with VS 2005. MS Windows. In debug mode, heap corruption is being detected.

The same code has ran fine on versions 6,7,8,9.

Is this a known issue? If not, i'll try to isolate the code.

thanks.

David.

Sorry, i didn't explain very well. The crash is on application exit, not in dgesv itself.

Matrix size has to be >=16. presumably a branch point in MKL. Anything less than 16 is fine.

Hello, David.

It occured due to some memory issue inside MKL. The issue has been fixed in Update3 that is coming soon.

Michael.
