This issue does not appear on 5.7 (possibly because of the different memory management routines).
Checked with both gcc and clang ASan.

On 5.5 trunk:

==13417==WARNING: AddressSanitizer failed to allocate 0x3fffffffffe0 bytes
==13417==AddressSanitizer's allocator is terminating the process instead of returning 0
==13417==If you don't like this behavior set allocator_may_return_null=1
Since this test specifically tests for OOM, the default ASan mode to crash is unsuitable here. I have added a workaround to Jenkins, but this ASan setting belongs to the server itself, per https://github.com/google/sanitizers/wiki/AddressSanitizerFlags, the proper fix would be adding __asan_default_options source function.
