 |  Workaround for random crash of userland binaries, as reported in

 |  If rtree.c and tcache.c are compiled with -O0, userland just works

 |  -DJEMALLOC_DEBUG to avoid random crash. Smells like compiler bug,

 |  Anyway, we need to pull this up into netbsd-9 asap.
 
 HEAD builds fine with gcc-8. Can you test it (and if the bug is still there)?
 
 Thanks,
