Oh, I found it...

Inside lib/uid_wrapper/wscript we have:

def build(bld):
    if not bld.CONFIG_SET("USING_SYSTEM_UID_WRAPPER"):
        # We need to do it this way or the library wont work.
        # Using private_library=True will add symbol version which
        # breaks preloading!
        bld.SAMBA_LIBRARY('uid_wrapper',
                          source='uid_wrapper.c',
                          cflags='-DNDEBUG',
                          deps='dl',
                          install=False,
                          realname='libuid-wrapper.so')

It's the cflags='-DNDEBUG' that does it :-(.

Any chance we can add a configure option that
turns this off (not sure how to waf-ify that :-) ?
