The memory_manager.cpp test was disabled for x86_64-pc-linux-gnu

I see this failure on Ubuntu 18.04 (both x86_64 and aarch64) and CentOS 7.7 (aarch64). I build LLVM with GCC 9.3. libelf and libffi development packages are provided by the operating systems.

This failure appears to affect newer distros. I see the same memory_manager.cpp failure with OpenSUSE Tumbleweed 20210428, gcc 10.3. The same system passes all tests under Ubuntu 20.4. Shilei suggested this could be related to Bug 48330 or elf64 using libffi.
