https://sourceware.org/bugzilla/show_bug.cgi?id=18824

            Bug ID: 18824
           Summary: fma spurious underflows
           Product: glibc
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
  Target Milestone: ---

fma functions can produce spurious underflow exceptions in some cases where the
product of the first two arguments is small and the third argument is large. 
E.g., for double on x86_64:

Failure: fma (-0x2.67e916f64646cp-948, 0xe.dabf64cc7e82p-4,
0xc.2c3bd123711bp+972): Exception "Underflow" set
