Sorry for the delay. Yes, I think that coping the pointers to shm was not properly done in the migration -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3812#issuecomment-2139701519 You are receiving this because you are subscribed to this thread.

Looked a bot over it and the `pcres` global was not allocated, by an assign to `*pcres` was done. On the other hand, I am not sure if it is enough, I guess the compiled regex has to be stored in shared memory and I cannot say it is done. Maybe @linuxmaniac can have more insights on it. With pcre3 library, there was a function from the lib that returned a contiguous block for the compiled regex that was then copied to shm. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3812#issuecomment-2071938830 You are receiving this because you are subscribed to this thread.
