[Bug fortran/39314] -ffpe-trap=invalid gives no FPE for acos(-5.0)

Note that the problem also appears for log, while it does not for acosh and
atanh:

real :: x = -5.0

! FPE is not thrown
print *, log(x)
print *, log10(x)
print *, acos(x)
print *, asin(x)

! FPE is thrown
!print *, sqrt(x)
!print *, atanh(x)
!print *, acosh(x)

end
