I used --enable-developer and all I got was this lousy build failure ...

Well, I solved this by just using --address-sanitizer and not using
--developer, but now I get this:

--------------------
==22284==You are trying to dlopen a /usr/lib64/ldb/modules/ldb/asq.so
shared library with RTLD_DEEPBIND flag which is incompatibe with
sanitizer runtime (see https://github.com/google/sanitizers/issues/611
for details). If you want to run /usr/lib64/ldb/modules/ldb/asq.so
library under sanitizers please remove RTLD_DEEPBIND from dlopen
flags.
--------------------

Can I safely remove RTLD_DEEPBIND?
