--- Comment #12 from Sebastiano Vigna <sebastiano.vigna at unimi dot it> ---
BTW, to further restrict the search I'm trying to replicate the bug with
-fsanitize=address, or at least to get to the problematic call under
-fsanitize=address, but it'll take a while. I have to recompile the gcc suite,
as the current version of libasan does not allocate more than 64GB (in Fedora,
libasan is built with gcc).
