-Subject: [PATCH] Fix #492: Potential double-free in gdImage*Ptr()
-
-Whenever `gdImage*Ptr()` calls `gdImage*Ctx()` and the latter fails, we
-must not call `gdDPExtractData()`; otherwise a double-free would
-happen.  Since `gdImage*Ctx()` are void functions, and we can't change
-that for BC reasons, we're introducing static helpers which are used
-internally.
-
-We're adding a regression test for `gdImageJpegPtr()`, but not for
-`gdImageGifPtr()` and `gdImageWbmpPtr()` since we don't know how to
-trigger failure of the respective `gdImage*Ctx()` calls.
-
-This potential security issue has been reported by Solmaz Salimi (aka.
-Rooney).
