[Bug libfortran/25370] New: Bad value for sqrt of double complex

[fxcoudert at gcc dot gnu dot org]

This code exhibit a weird dependance on whether it is statically linked or
dynamically linked:

$ cat foo.f90 
complex c
double complex d

c = (-1., 0.)
print *, c, sqrt(c)
d = c
print *, d, sqrt(d)
end

$ ./bin/gfortran -static foo.f90 && ./a.out
 ( -1.000000    ,  0.000000    ) (  0.000000    ,  1.000000    )
 ( -1.00000000000000     ,  0.00000000000000     ) (  0.00000000000000     , 
1.00000000000000     )
$ ./bin/gfortran foo.f90 && ./a.out
 ( -1.000000    ,  0.000000    ) (  0.000000    ,  1.000000    )
 ( -1.00000000000000     ,  0.00000000000000     ) ( 1.397677071793657E-312,
