Failure of DGESVXX

Hi all,

I want to report a problem with DGESVXX.
When I compile my program that uses this routine with the option "initialize stack variables to an unusual value"
it fails when run with this message: forrtl: error (72): floating overflow. Without this option the program runs without problems.
This makes me doubt DGESVXX.
With DGESVX or GESVX there is no such problem.
I use VS 2017 and an Intel Fortran compiler 17.0 with update 6. 64 bit program.

Regards,

Hi,

We don't know such issue at this moment. Do you have the example of this case which we may compile and check the problem on our side?
