similar known bug(s)
The fdim(x, y) family of functions shall determine the positive difference between their arguments. According to LSB, if the result overflows then fdim() shall fail and shall set ERANGE error code. But on the target machine, the functions set error code EOK instead of ERANGE when overflow occurs.
