Subject: [PATCH] Fix crash in midi_latency_test

`s` points to a constant string literal in the current code (which is in practice
just a pointer in some read-only memory). The next line `s[2] = c;` either
crashes or just gets completely removed by the compiler as it attempts to
write to read-only memory.
