 Summary: Occasional segfaults in System.Drawing.Image:Save
 When saving bitmaps to PNG files, We are getting segfaults occasionally. We
 have not yet found a way to reproduce the bug reliably, so we cannot offer
 a test case.

 Maybe I should mention that we haven't had this problem with the
 version installed previously (1.1.9 from CVS).

+r58160 fixed a bug related to the encoder. Recently freed memory was
+being reused, which *could* explain your occasional problem.
+Please try to duplicate this problem with SVN HEAD, or with a newer
+version of 1.1.13 or 1.1.14 (when they get released).
+Otherwise it would be useful if you could attach a small (self
+contained, no ASP.NET) sample that can duplicate the problem (even if
+it doesn't every time).
