It looks the problem is not "sizeof(max_align_t) on i386 is 12 bytes"
but "upstream lib/isc/jemalloc_shim.h (local implementation of
non-standard mallocx() and variants) assumes sizeof(max_align_t)
is power of 2 (or multiple of 8)".

Using in-tree jemalloc(3) by enabling HAVE_JEMALLOC explicitly in
src/external/mpl/bind/include/config.h also fixes the problem
(I'm not sure why it has been disabled by default):
