| Platform | Linux | OS | Debian | OS Version | 10 (buster) |
| Product Version | 4.0.2 | ||||
| Fixed in Version | 4.0.6 | ||||
| Summary | 0000613: segfault, error 4 in libc-2.28.so, when using 'enable_pool_hba' | ||||
| Description | Segmentation fault in Debian 10 when using 'enable_pool_hba'. I suspect of the option 'samenet' in pg_hba.conf because after replacing it with IPs, there is no error. | ||||
| Steps To Reproduce | 1. Use 'enable_pool_hba' 2. Use the following for pg_hba.conf " local all postgres md5 local test myuser md5 local all all peer host all all 127.0.0.1/32 md5 host all all ::1/128 md5 host all postgres samenet md5 host replication replicator samehost reject host replication replicator samenet trust host test myuser samenet md5 " 3. use the following for " local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust host all postgres samenet md5 host test myuser samenet md5 " 4. Connect to delegate_IP using 'psql'. Ex " psql -h 172.24.0.100 -U -p 5432 postgres " Segfault will happen and output will be: " psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. " | ||||
