Major - P3 When turning on the import functionality in test/format an assert gets hit:
[2021/05/07 04:44:57.277] [1620362689:383685][40914:0x7f7ded7fa700], t: __posix_file_read, 423: !pfh->direct_io || S2C(session)->buffer_alignment == 0 || (!((uintptr_t)buf & (uintptr_t)(S2C(session)->buffer_alignment - 1)) && len >= S2C(session)->buffer_alignment && len % S2C(session)->buffer_alignment == 0) [2021/05/07 04:44:57.277] [1620362689:383711][40914:0x7f7ded7fa700], t: __wt_abort, 28: aborting WiredTiger library
The backtrace shows as

It seems to be trying to do a __wt_copy_and_sync and fails when reading in the import.wt file, the information around the assert shows as:
(gdb) print $3->buffer_alignment $4 = 512 (gdb) print pfh->direct_io $5 = true
