That might help in certain narrow other cases, but I suspect that it is a
way off tangent in this case, after looking at the stack trace.

The process is dying inside pthe latform implementation of memcpy of
inflate from zlib; unless the bug is reproduceable independent of the
contents, any modification done by contents anonymizer is very likely to
make this particular issue go away, don't you think?
