SYMPTOMS
When console STDIN and STDERR are being redirected in a 16-bit MS-DOS-based program, the program may stop responding (hang). For example, if a 32-bit Windows-based program uses two pipes (for read and write) and redirects these pipes as console STDIN and STDERR for data communication with a 16-bit MS-DOS-based program, and the 32-bit Windows-based program and the 16-bit MS-DOS-based program are interdependent for data transfer, a deadlock may occur.
