@Beliavsky I tested the latest snapshop of version 15 from equation.com, and got a different error:
stdlib_linalg_pinv.fypp line 77

do concurrent (i=1:m,j=1:k); u(i,j) = s(j)*u(i,j); end do

after changing this into its 3 lines

do concurrent (i=1:m,j=1:k)
     u(i,j) = s(j)*u(i,j)
end do

it compiled and the tests passed.

It seems to me as an instability on the snapshop side, the latest stable version 14 has no issues.

I downloaded the latest version of fpm, and the problem has disappeared. So this issue can be closed.
