             Bug #: 14857
           Summary: complex divide wrong
           Product: clang
           Version: 3.1
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: tydeman at tybor.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


C99 and C11 Annex G has:
  G.5.1#4, item 2:
  if the first operand is an infinity and the second operand is a
  finite number, then the result of the / operator is an infinity;

clang violates that for many cases, such as:
  (0.0+inf*I)/(0.0+0.0*I)
  (0.0+inf*I)/(0.0+maximum*I)
  (0.0+inf*I)/(min+max*I)
