            Bug ID: 16408
           Summary: ldbl-128ibm expm1l bad overflow handling
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

The ldbl-128ibm expm1l implementation produces NaN results on some overflowing
inputs (maybe some non-overflow cases as well):

Failure: expm1 (0x2.c5c4p+12): Exception "Invalid operation" set
Failure: Test: expm1 (0x2.c5c4p+12)
Result:
 is:         qNaN
 should be:   inf   inf
