SIGPIPE

[Francesco Potorti`]

While running Emacs (pretest version) under gdb, I got this:

Program received signal SIGPIPE, Broken pipe
0x403a83e4 in write () from /lib/libc.so.6
(gdb) bt
#0  0x403a83e4 in write () from /lib/libc.so.6
#1  0x00000000 in ?? ()
(gdb) 

This has occasionally happened to me since version 21 when signing a
meail messagge with mailcrypt (which uses gpg).

>From the backtrace it seemed to me that the stack was smashed, so I
continued the process, expecting to see it abort.  Instead, it continued
and displayed a message:

mc-gpg-process-region: SIGPIPE raised on process *GPG*; closed it
