           Summary: Assert/Crash when using arrays of 64k elements or more
                    in structs
           Product: new-bugs
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

Using arrays of 64k or larger overflows the unsigned short SDNode::NumValues
variable, and leades to asserts/crashes.  Simple test case:

; ModuleID = 'Q'

%0 = type { i64, i64, [65536 x double] }
@global_subject5747_522547216 = internal hidden global %0 zeroinitializer


define internal void @on_1_522492064(i64 %VALUE_0) {
entry:
  store %0 zeroinitializer, %0* @global_subject5747_522547216
  ret void

}
