This could be related to the broken -ffp-contract=fast default in GCC.

We see similar failures with -march=x86-64-v3 (which also includes FMA):

FAIL: gsl_spmatrix_complex_float_scale_columns[53,107](COO) real (6.17895793914794922 observed vs 6.17895841598510742 expected) [21704]
FAIL: gsl_spmatrix_complex_float_scale_columns[53,107](COO) imag (144.412811279296875 observed vs 144.412826538085938 expected) [21709]

See the attached file build.log for the full list.

Maybe the solution is to increase the ULP limit for these test results?

spmatrix test failure fixed in commit 15ea0bf6bb19c048010fed2879ff2669ed37a1b7

Note that gsl_linalg_hessenberg is deprecated and is replaced by gsl_linalg_hessenberg_decomp

from J.D.Lamb =at= johndlamb =dot= net

I notice that gsl_linalg_hessenberg is still not declared in any header file. Presumably the intention was to declare it in gsl_linalg.h

Also I get the following fails in spmatrix:
