SIGSEGV while uploading to S3 for part > INT_MAX #47679
Description
Reproducer:
INSERT INTO FUNCTION s3('https://test.s3.us-east-1.amazonaws.com/clickhouse/test.csv', '', '', 'TSV')
SETTINGS s3_truncate_on_insert = 1, s3_max_single_part_upload_size = '10Gi'
SELECT repeat('a', 1024)
FROM numbers((pow(2, 30) * 5) / 1024)
SETTINGS s3_truncate_on_insert = 1, s3_max_single_part_upload_size = '10Gi'Note, that usually it is not a problem since multi part upload is used, but when you turn it OFF you can see the problem.
And the problem is the stringstream::gcount breaks stringstream when it holds more the INT_MAX
