+have been removed.

+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).
