I get a seg fault when adding group entries with some regex-constrained attributes. This is RE24 with the recent fixes for slapo-constraint. The constraint setup works with 2.4.31.

Strange thing is that the entry is added to the database. So it seems to me that the seg fault happens after that while checking constraints for what slapo-memberof does?

As often this is a complex customer setup. So it's not that easy to narrow down the config and strip aways private customer data in a full traceback. I will do if really necessary.

Maybe this gives a first hint where to look:

constraint_check_restrict (op=0x7faecbffdd80, c=0xf8c550, e=0x0) at constraint.c:713

Hello Michael,

can you please provide a full backtrace of thread 1? A quick look suggest that there's something wrong, because constraint_check_restrict probably should not be called with e=0x0, but I'm unable to tell anything else with such restricted information.

Also, if the problem is in my fix, it should be fairly easily reproducible with just a few slapadds with the right data.

Cheers,
