Actually the test seems to crash most of the times while releasing
tex2 (e.g. http://test.winehq.org/data/529e4154a34a5a774fe7036552ffbb060740da90/
win81_newtb-w864-64/d3dx9_36:core.html), sometimes while releasing tex1
(http://test.winehq.org/data/9ef5c9c0090f17df5bfd794485019fb8bf9a7e25/
win21H1_newtb-w10pro64-zh-CN-64/d3dx9_36:core.html). At any rate,
there is probably some weird bug in native but we don't care much
about its details and I don't see any reason not to introduce the
missing End().
