// 4530: C++ exception handler used, but unwind semantics are not enabled. Specify -GX
|
||
|
|
//
|
||
|
|
// We disable this because we use exceptions and do *not* specify -GX (USE_NATIVE_EH in
|
||
|
|
// sources).
|
||
|
|
//
|
||
|
|
// The one place we use exceptions is around construction of objects that call
|
||
|
|
// InitializeCriticalSection. We guarantee that it is safe to use in this case with
|
||
|
|
// the restriction given by not using -GX (automatic objects in the call chain between
|
||
|
|
// throw and handler are not destructed). Turning on -GX buys us nothing but +10% to code
|
||
|
|
// size because of the unwind code.
|
||
|
|
//
|
||
|
|
// Any other use of exceptions must follow these restrictions or -GX must be turned on.
