[Lapack] lapack-3.1.1 / secondtst.f, dsecndtst.f / number of DAXPY, SAXP

Hello,

 

Long story short: I noticed some "*** Error:  Time for operations was
zero" messages when running the testdsecnd binary so I checked the code
(secondtst.f and dsecndtst.f as well).

 

I am not a fortran expert, but I noticed that 1,000,000 DAXPY / SAXPY
operations should be performed but NMAX is set to 100 and ITS is set to
5000 ... Is it a typo, or did I miss something ?

 

I don't get any error messages with the following patches:
