Alexey says:

We have a test crash with ASan, because it tries to allocate too much, and ASan doesn't allow that.

We need to change the default behavior:

==45420==WARNING: AddressSanitizer failed to allocate 0xffffffffaffff6a0 bytes
==45420==AddressSanitizer's allocator is terminating the process instead of returning 0
==45420==If you don't like this behavior set allocator_may_return_null=1
==45420==AddressSanitizer CHECK failed: /SourceCache/clang/clang-603.0.12/src/projects/compiler-rt/lib/sanitizer_common/sanitizer_allocator.cc:149 "((0)) != (0)" (0x0, 0x0)
