### Description Build kamailio master branch and define `TLS_MALLOC_DBG` in the `tls` module. There is an immediate segfault on startup. ### Troubleshooting Build kamailio master branch without `TLS_MALLOC_DBG` in the `tls` module. kamailio can start normally. #### Reproduction * use a distro with OpenSSL 3, e.g., AlmaLinux 9, Debian 12 * checkout kamailio master branch * in `src/modules/tls/tls_init.c` define `TLS_MALLOC_DBG` * build and run kamailio #### Debugging Data ``` Program terminated with signal SIGSEGV, Segmentation fault. #0 0x0000000000000000 in ??
