Status variables were initialized in the collect phase and some variables were later freed in the print functions. A "struct wt_status" used to be sufficient for the output phase to work. It was designed to be filled in the collect phase and consumed in the output phase, but over time some fields were added and output phase started filling the fields. A "struct wt_status_state" that was used in other codepaths turned out to be useful in the "git status" output. This is not tied to "struct wt_status", so filling in the collect phase was not consistently followed. Move the status state structure variables into the status state structure and populate them in the collect functions. Create a new function to free the buffers that were being freed in the print function. Call this new function in commit.c where both the collect and print functions were being called. Based on a patch suggestion by Junio C Hamano. [1] [1] https://public-inbox.org/git/xmqqr2i5ueg4.fsf@xxxxxxxxxxxxxxxxxxxxxxxxx/ Signed-off-by: Stephen P.
