[Rd] Request for help with UBSAN and total absense of CRAN response

[Dirk Eddelbuettel]

CRAN has a package of mine in upload limbo because it failed UBSAN.

I am not entirely ignorant on the topic of sanitizers and SAN / ASAN / UBSAN;
we created not one but two Docker containers with ASAN and USBAN:

   https://registry.hub.docker.com/u/rocker/r-devel-san/
   https://registry.hub.docker.com/u/rocker/r-devel-ubsan-clang/

as well as predecessors to them in earlier Docker repos.

Yet I fail to recreate the errors reported by CRAN:

   http://www.stats.ox.ac.uk/pub/bdr/memtests/UBSAN-clang-trunk/RcppAnnoy/tests/runUnitTests.Rout
   http://www.stats.ox.ac.uk/pub/bdr/memtests/UBSAN/RcppAnnoy/tests/runUnitTests.Rout

I asked politely (and twice) for help with the corresponding compiler
configuration(s).  But CRAN is of course way above communicating with mere
mortals such as yours truly.

So I have no recourse other than to spam all of you: if anybody here has a
working UBSAN setup which can replicate the issue seen in the (rather small)
RcppAnnoy package?

Erik (upstream for Annoy, CC'ed) and I would be most grateful.  We do not
like being held hostage on an error report we cannot replicate and for which
we do not receive any help (or even further communication) whatsoever.
