Failed to initialize avrofile, fatal signal 11

Hi,

I'm having an issue while starting maxscale when I set up avrorouter service :

error : Failed to initialize avrofile.
error : Fatal: MaxScale 2.0.3 received fatal signal 11. Attempting backtrace.

Context :

1) I setup a binlogrouter service and replicate binlogs from my master mariadb node, binlog started at index 32
2) I used cdc_schema.go to generate avro schema files (some create table statements where missing)
3) I setup avrorouter service and try to start but it fail

Here is my configuration :

1. The Replication Proxy service

[replication-service]
type=service
router=binlogrouter
router_options=server_id=4000,master_id=3000,binlogdir=/var/lib/maxscale/binlog/,mariadb10-compatibility=1,
user=user
passwd=pass

1. The Avro conversion service

[avro-service]
type=service
router=avrorouter
source=replication-service
router_options=binlogdir=/var/lib/maxscale/binlog/,avrodir=/var/lib/maxscale/avro/,filestem=mariadb-bin,start_index=32,
