[bug] failed file open gives segfault

[Erik Sandberg]

Hi,

If you let foo.ly create midi output, like
\score {
  {c d e }
  \midi {}
}

and then create an unwritable foo.midi file (e.g. echo>foo.midi;chown root 
foo.midi, or just mkdir foo.midi), then lilypond segfaults:


GNU LilyPond 2.5.18
Processing `foo.ly'
Parsing...

warning: No \version statement found.  Add

\version "2.5.18"

for future compatibility.

Interpreting music...
MIDI output to `foo.midi'...Segmentation fault

However, lily handles unwritable foo.ps or foo.pdf perfectly.
