It's that valgrind check is failed. I've tried to restart it twice with the same result.

total heap usage: 10,089,708 allocs, 9,941,721 frees, 3,025,851,569,279,572,588 bytes allocated

The same job in different PR is green.

It seems that we have some leak, I've pushed valgrind with -s: https://github.com/mymarilyn/clickhouse-driver/actions/runs/9797329602

The error occurred just because pyarrow was installed.

I'm going to delete it.

I tried debugging but got no results.
It seems beyond my ability.
Can we ignore the problem for now?

By the way, pandas has PDEP-10: PyArrow as a required dependency for default string inference implementation

PyArrow becomes a required runtime dependency starting with pandas 3.0

This might cause problems in the future.
