(DER - 2019/08/27, HDFFV-10892)
+ - Torn pread/pwrite I/O would result in read and write corruption.
+
+ In the sec2, log, and core (with backing store) virtual file drivers
+ (VFDs), the read and write calls incorrectly reset the offset parameter
+ on torn pread and pwrite operations (i.e., I/O operations which fail to
+ be written atomically by the OS). For this bug to occur, pread/pwrite
+ have to be configured (this is the default if they are present on the
+ system) and the pread/pwrite operation has to fail to transfer all
+ the bytes, resulting in a multiple pread/pwrite calls.
+
+ This feature was initially enabled in HDF5 1.10.5 so the bug is
+ limited to that version.
