After #24483 had been merged the only place where the allocation may
fail is the insert into PODArray in DB::OwnSplitChannel::log, but this
MR ignores the errors in this function, so to check new behaviour
separate server is required.
Some code does not expect from the logger code to throw, and this can
lead to the problems like:
- marking distributed batch as broken (in
StorageDistributedDirectoryMonitor)
- some MergeTree code may also be affected.
So instead of throwing the exception, it will be logged to the stderr
(if it is possible).
