[gnuastro-commits] master 6bca933: Initialized BuildProgram's internal optimize and warning strings

[Mohammad Akhlaghi]

branch: master
commit 6bca933d8792a5faefe22fc08fb978494ab9dde4
Author: Mohammad Akhlaghi <address@hidden>
Commit: Mohammad Akhlaghi <address@hidden>

    Initialized BuildProgram's internal optimize and warning strings
    
    These two strings were not initialized in BuildProgram, which could give
    undefined behavior. They are now both initialized to NULL.
    
    Also, in the documentation, an example for optimizations was given.
