Hi Quanah, I have followed your instructions. As you can check the slapd
binary is not stripped:

-bash-3.00# file slapd
slapd:          ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, not stripped

The backtrace of the slapd process is the following:

<<< dnPretty: <cn=Eduardo Izaguirre
Assertion failed: ( nvals == NULL && (*a)->a_nvals == (*a)->a_vals ) ||
( nvals != NULL && ( ( (*a)->a_vals == NULL && (*a)->a_nvals == NULL )
|| ( (*a)->a_nvals != (*a)->a_vals ) ) ), file attr.c, line 480

Hi Eduardo,

Please test with the current CVS of REL_ENG_2_4.  Please build without
optimization, and with debugging symbols.  Make sure you don't strip
slapd on install.  If you can repeat this with current CVS, please
provide a gdb backtrace of the non-optimized, non-stripped slapd.
