I looked hard, and could not find the reason of a failure here. The
bakctrace of the new one is a little different than previous one, but I
am not sure why it crashes. Until I have a reproduction scneario, I may
not be able to fix this. How about a core? However, a core will have
values which you are trying to mask with sanitize.
