Re: (ITS#7150) SEGFAULT in openldap-2.4.28 & 2.4.29
That was my first try.
I have used the option --enable-debug in the configure command, which
seems to produce AC_CFLAGS = -g -O2, itself reinjected in CFLAGS =
$(AC_CFLAGS) $(DEFS) in the Makefile.
However this has lead to an unusable stacktrace. Thus I preferred using
the binary file (with debug symbols) pointed by openldap-src/servers/slapd :
/opt/openldap-src/servers/slapd/.libs/lt-slapd
This gave me the stacktrace I first sent.
I have used /opt/openldap-src/servers/slapd/.libs/slapd instead, and it
seems to give a better stacktrace. (joined in this mail)
Thank you for your help.
