I am running the BLAS test from the reference implementation but linked against OpenBLAS, then SNRM2 and DNRM2 fail with INCX=0 and SCNRM2 and DZNRM2 even fail in cases where INCX!=0.

Even a minimal example:

#include <stdio.h>

extern float snrm2_(const int *n, const float *x, const int *incx);

int main() {
    float x[] = {1};
    int n = 4;  
    int incx = 0; 

    float norm = snrm2_(&n, x, &incx);

    printf("norm: %f\n", norm);

    return 0;
}

returns 0 instead 2.

Mixing these is currently not expected to work, as Reference-BLAS has changed the implementation of NRM2 and OpenBLAS' kernels are still using the old one. (#4188 (comment))

The main difference in the Ref-BLAS is the scaling in case of numerically critical situations. the mini example does not touch this, so this is not covered by the different implementation ideas.

Thought OpenBLAS already had an utest for that, but apparently not...

As far as I can tell from the calculated "true" values in cblat1.f/zblat1.f, the reported failures for INCX != 0 appear to be due to some mishandling of "infinity" results in the test itself - which also explains why their printed test ratio (TRAT) is given as NaN
