[GitHub] [age] bravius opened a new issue, #235: MERGE followed by SET causes segfault
bravius opened a new issue, #235:
URL: https://github.com/apache/age/issues/235
**Describe the bug**
MERGE followed by SET causes server process segfault.
**How are you accessing AGE (Command line, driver, etc.)?**
Bundled Node 'pg-age' driver.
**What data setup do we need to do?**
```pgsql
...
SELECT create_graph('test');
SELECT create_vlabel('test', 'node');
SELECT * FROM cypher('test', $$ CREATE (n:node {name: 'Jason'}) RETURN n $$) AS (n agtype);
...
```
**What is the necessary configuration info needed?**
None.
**What is the command that caused the error?**
```pgsql
SELECT * FROM cypher('test', $$ MERGE (n:node {name: 'Jason'}) SET n.name = 'Lisa' RETURN n $$) AS (n agtype);
```
```
LOG: server process (PID 4853) was terminated by signal 11: Segmentation fault
DETAIL: Failed process was running: SELECT * FROM cypher('test', $$ MERGE (n:node {name: 'Jason'}) SET n.name = 'Lisa' RETURN n $$) AS (n agtype)
LOG: terminating any other active server processes
WARNING: terminating connection because of crash of another server process
DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
HINT: In a moment you should be able to reconnect to the database and repeat your command.
LOG: all server processes terminated; reinitializing
LOG: database system was interrupted; last known up at 2022-06-20 20:15:58 UTC
FATAL: the database system is in recovery mode
LOG: database system was not properly shut down; automatic recovery in progress
LOG: redo starts at 0/521B0A0
LOG: invalid record length at 0/526E288: wanted 24, got 0
LOG: redo done at 0/526E250
LOG: last completed transaction was at log time 2022-06-20 20:16:12.938992+00
LOG: database system is ready to accept connections
```
**Expected behavior**
Execute cypher query with no crashy crashy.
**Environment (please complete the following information):**
- postgresql with age extension running in Docker container on Windows 10 and WSL2
- Compiled from master.
**Additional context**
None.

Could this be related to https://github.com/apache/age/discussions/232#discussioncomment-2911728, where the return value differs depending on whether a node exists before executing a MERGE?
