Let me know if this doesn't have what you need.
Can you also print *ml and *ml->sml_desc ? It looks like you're performing a modify on an attribute that back-ndb doesn't already know about.

I tried to build openldap without compilier optimiations, but its ignoring CFLAGS and CXXFLAGS when i set them to
export CFLAGS = "-g -ggdb"
export CXXFLAGS=$CFLAGS
use make AC_CFLAGS=-g
and still passes -O2, doesn't pass -ggdb. what am I missing to disable optimizations when building.

Unfortunately this trace is nonsensical because of the compiler optimizations. It shows a call path that simply doesn't exist (connection_read -> syslog -> connection_operation).
Please try again with all optimization turned off in your build.
