Hello, I build openldap 2.4.7 a few weeks ago, and 2.4.9 yesterday, with 2.4.7 and 2.4.9, without any my patches, just a clean build. After adding my custom schema, uploading my data from production version, and indexing, I still have it crash with some specific search - I was hoping 2.4.9 have this resolved, seems not, so posting this.
I distracted example search which always causes segfault, each time, 100% reproductible.
Have nice reading.. :) I'd be glad to report I replaced my production with 2.4.x series, thanx upwards for any hint :) Should I perform some gdb-enabled build, and post some core? I'm currently ahead to do this.

Hello, I build openldap 2.4.7 a few weeks ago, and 2.4.9 yesterday, with 2.4.7 and 2.4.9, without any my patches, just a clean build. After adding my custom schema, uploading my data from production version, and indexing, I still have it crash with some specific search - I was hoping 2.4.9 have this resolved, seems not, so posting this.
Build with debugging symbols, gdb it, and supply the backtrace.

I added -ggdb and made sure symbols are not stripped during build process. Anyway backtrace still looks like the one I've already posted, do I miss something ?

slapd is stripped when it is installed. I don't remember the "official" way to prevent that, but one way which seems to work is cd servers/slapd make STRIP= install

Just to be clear, I use
make install STRIP=""
