Multi-Master - rdbcompression seg faults #204
Description
When running keydb 6.0.8-rc1 configured as multi-master with 6 nodes and rdbcompression enabled, the child processes for executing a BGSAVE segfaults causing replication to fail.
I am compiling from source and building this into an Alpine container, so I may have missed a dependency somewhere but I can't tell.
Disabling this feature causes everything to work as expected.
To Reproduce
Setup 6 keydb processes in a full mesh, multi-master mode with rdbcompression enabled.
