Workstation: 9.0.2 (guest tools updated)
Host: Windows 7 SP1 64-bit
Guest: Ubuntu 12 32-bit (1 CPU, 1 GB RAM)
Steps to reproduce:
1) Add a shared host folder to the guest.
2) Copy a large file to the folder (tested with Workstation setup file).
3) Inside the guest, copy the file in the shared folder and paste it to the same folder at least 10 times.
4) Data corruption should occur in some of the duplicated files (100 KB of zeros at a random position).
