Hi,

The midi code causes memory corruption in 2.7.35. For example:

\version "2.7.35"

\score {
 {c4}
        \midi {
        }
}

gives the following here:

GNU LilyPond 2.7.35
Processing `foo.ly'
Parsing...
Interpreting music...
MIDI output to `foo.midi'...
Track... Segmentation fault

By randomly manipulating the input, the crash can be made to happen as early 
as:

Processing `foo.ly'
Parsing...
Interpreting music... *** glibc detected *** malloc(): memory corruption: 
0x08616db0 ***
Aborted
