--- Comment #4 from Florian Weimer <fweimer at redhat dot com> ---
Apparently, the expectation here is that interposed mallocs preempt
__libc_memalign as well (it is exported for this purpose, I assume). But this
is totally undocumented. tcmalloc interposes it, jemalloc and Emacs malloc do
not. (tcsh malloc does not even interpose memalign.)
