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

It looks to me like GDB has got confused by some legitimate
stack contents. Perhaps the `write' function does not set up
a normal stack frame. It would be good to change GDB to
handle what `write' actually does on the stack.
What platform is this? What GDB version?
