Comment(by batterseapower):

 Simon's patch zaps the wrong case_bndr. The case_bndr returned by
 getProxies is the raw, unzapped, one from the Case expression being
 analysed. The robust solution is to zap the occinfo in wrapProxy itself.

 I've attached a patch to HEAD that fixes the bug. I would have just pushed
 it but the repo is still locked.
