Tom Lane c168ba3112 Free libxml2/libxslt resources in a safer order. ... Mark Simonetti reported that libxslt sometimes crashes for him, and that swapping xslt_process's object-freeing calls around to do them in reverse order of creation seemed to fix it. I've not reproduced the crash, but valgrind clearly shows a reference to already-freed memory, which is consistent with the idea that shutdown of the xsltTransformContext is trying to reference the already-freed stylesheet or input document. With this patch, valgrind is no longer unhappy. I have an inquiry in to see if this is a libxslt bug or if we're just abusing the library; but even if it's a library bug, we'd want to adjust our code so it doesn't fail with unpatched libraries. Back-patch to all supported branches, because we've been doing this in the wrong(?) order for a long time.		2014-11-27 11:13:29 -05:00
