memory leak in latest version of MKL

Dear all,

I checked my program by Intel's 'Memory and Thread Debugger' and found the function 'dsygv' leak memory when use latest version MKL. The same code compiled by version 2016.3.223 is OK. The build environment is windows 7 64bit + VS2013 64bit + Intel parallel studio 2016 (this program is OK) and Windows 10 64bit + VS2017 64bit + Intel parallel studio 2019.5 (this program leaks memory). Could anyone help me to take a look at the problem?

 

Thanks,

Tang Laoya

this is an unknown issue, thanks for letting us know. The quick testing didn't show the problem. I used the Intel Inspector to detect such problems. 

Could you try the latest MKL 2019 u5 or give the reproducer which we may use to check the problem on our side!

Dear Gennady,

I just tested the latest MKL2019.5 and found the problem. The same code with version 2016 is OK.

Thanks,
