static void FDWrite(int fd, const char* buf, size_t len) {
  while (len > 0) {
    ssize_t r;
    NO_INTR(r = write(fd, buf, len));
    RAW_CHECK(r >= 0, "write failed");
    buf += r;
    len -= r;
  }
}

RAW_CHECK failed.

[James Page (james-page)]

However:

        buf = 0x7f853d018010 ""
        len = 64

looks suspicious to me.

[James Page (james-page)]

Hmm no errno to inspect which makes things awkward.

[James Page (james-page)]

On the assumption you where profiling pulseaudio do you have a test case I can use to reproduce this?

[Daniel van Vugt (vanvugt)]

It was an accident :)

I guess pulseaudio was spawned from gnome-shell, which is what I was profiling. I don't have any interest in pursuing this bug.
