straces between 2 runs that are good only differ in some system
call, and they all have to do with either the pid changed or
the time as clock_gettime(), or the name of the tempary directory
the use.
Anyway, this seems to be first place where they are different in
what they do:

So, the change from tar.crQir1 to tar.JSQLy3 seems to be
normal. But then for some reason itstead of doing an
mkdir(), it does an lstat() instead.
It seems that it's this code in extract.c that behaves
different:
if (incremental_option)
/* Read the entry and delete files that aren't listed in the archive. */
purge_directory (file_name);
else if (typeflag == GNUTYPE_DUMPDIR)
skip_member ();
mode = (current_stat_info.stat.st_mode |
(we_are_root ? 0 : MODE_WXUSR)) & MODE_RWX;
while ((status = mkdir (file_name, mode)))
My guess is that's somewhere in the purge_directory() call
that behaves differently for some reason, but I'm not sure
why yet. Will take a closer look tomorrow.
Both straces attached.
