We need to hand the "remerge_objdir_location" off to the "rev_info" struct, but that seems separate from its lifetime. Re my [1] & [2] I like Neeraj's "atexit cleanup" approach better, perhaps that makes your cleanup in log-tree.c redundant or easier? Per [2] it looks like you need to "hand off" the "remerge_objdir_location", so having the struct live in tmp-objdir.h as I suggested in [2] might make that work... 1. https://lore.kernel.org/git/87v92lxhh4.fsf@xxxxxxxxxxxxxxxxxxx/ 2. https://lore.kernel.org/git/87r1d9xh71.fsf@xxxxxxxxxxxxxxxxxxx/
