| Summary | 0004324: segfault on launch of ircd | ||||
| Description | Upon new installation of 3.4-alpha1 released tarball, as well as using the latest github sources, starting the ircd with an existing configuration causes a seg fault with core dump on launch via ./unreal start. This occurs regardless of if it's installed to a seperate directory or compiled and used within the source tree. | ||||
| Steps To Reproduce | Configure and make unreal Re-use existing ircd configuration with the proper changes noted, copying over SSL certificates. Receive coredump. | ||||
