--- Comment #1 from Steven Schveighoffer <schveiguy at gmail.com> ---
I would suggest this be resolved as WONTFIX

As I said in the forums, ignoring SIGPIPE is a process-wide setting, not
suitable for all environments, so D should not be doing this to intialize the
runtime.

2 examples come to mind:

- starting a child process will inherit the signal ignoring, which means you
alter the default behavior of those processes (which may depend on SIGPIPE
being triggered)
- Other libraries might depend on SIGPIPE not being ignored.

I think the correct mechanism is to manually ignore the signal on program
startup if that is your preference.
