Working in the 43max bibisect repository on debian-stretch, I see from
`git bisect good` (lines rewrapped) ...

So ZCodec::ReadAsynchron was wrong in using a persistent
mpIStm after all
The fun thing is that with the (only) call-site to
ReadAsynchron in PNGReaderImpl::ImplReadIDAT
(vcl/source/gdi/pngread.cxx) passing in rIStm references
to stack-allocated SvMemoryStream instances, mpIStm could
point to an old, destroyed instance from a previous call,
but which would have been located at exactly the same
stack address as the currently passed in rIStm, so the
wrong mpIStm->Read call would effectively behaved exactly
the same as a correct rIStm.Read call.
This went unnoticed "since the beginning" until
AddressSanitizer's UseAfterReturn check came along...
