Segfault when both stdout/stderr are full (or closed?)

There are a bunch of (closed) issues for problems that result when an output stream is closed or full:

• #43 (closed)
• #326 (closed)
• #407 (closed)

In ecl-21.2.1, for example, redirecting stdout and stderr, individually, to a full device produces the following results:

$ echo "syntax error" | ecl >/dev/full

However, redirecting them both still produces a segfault:

$ echo "syntax error" | ecl >/dev/full 2>&1
Segmentation fault

Just adding this to the list since it doesn't seem to have been covered by any of the previous tickets.
