* When SIGCHLD is trapped, and a SIGCHLD trap handler runs when
a pending `read -t' invocation times out and generates SIGALRM,
bash can crash with a segmentation fault.
* When converting a multibyte string to a wide character string
as part of pattern matching, bash does not handle the end of
the string correctly, causing the search for the NUL to go
beyond the end of the string and reference random memory.
Depending on the contents of that memory, bash can produce
errors or crash.
* The <&n- and >&n- redirections, which move one file descriptor
to another, leave the file descriptor closed when applied to
builtins or compound commands.
- Use screen to provide a controlling terminal for running the
