[bug-gv] gv-3.7.2: Possible pointless call to unlink ?

[David Binderman]

Hello there,

I just ran the static analysis tool cppcheck over the
source code of gv-3.7.2. It said

[gv-3.7.2/src/ps.c:612]: (error) Dereferencing 'tmp_file' after it is 
deallocated / released

The source code is

    fclose(tmp_file);
    unlink((char*) tmp_file);

Since the file is only read, I can't see any point in unlinking it.
Suggest new code

    fclose(tmp_file);

Regards
