patch: dwarf_getsrclines.c: Fix unitialized usage of filelist
I'm getting this error with 0.172:
dwarf_getsrclines.c: In function 'read_srclines':
dwarf_getsrclines.c:1074:7: error: 'filelist' may be used uninitialized in this
function [-Werror=maybe-uninitialized]
free (filelist);
^~~~~~~~~~~~~~~
It seems that gcc is right here as there is "ifs" that go to "out" (where
filelist is freed) before freelist is initialized. I fixed by just moving
filelist initialization to before the first usage of "goto out;". Maybe there
is a more elegant approach.
