Segmentation fault when function declaration begins at start of source file

[JonathanFoo0523]

Applying MUSIC to program

int main(void) {
  return 0;
}

results in segmentation fault.

I believe this occurs when the first function declaration coincides with the start of the source file (1:1). MUSIC fails to identify the start of a new declaration during the check here, fails to initialize the return statement list here, and subsequently triggers a segmentation fault when modifying the last element of the empty return statement list here
