Any case where a libm function produces errors exceeding the maximum 
accepted in ulps files (9 ulps for most formats, 16 for IBM long double), 
in any rounding mode, measured in the way the libm testsuite does 
(comparing against a correctly rounded result for that rounding mode, not 
against an infinite-precision result) should be reported as a bug to 
Bugzilla if there isn't already a bug open for inaccuracy of that 
function.
