commit 46ee7cc6c642906e6500a5451e8059e35f480aff

    Compilation warnings: fixed by initializing variables
    
    After the 0.15 release, the Anaconda server successfully built Gnuastro
    0.15 on a macOS system. However, when inspecting the log, I noticed two
    "may be used uninitialized" warnings.
    
    With this commit, those two variables are initialized to NULL to suppress
    this warning in the future builds on macOS.
