Oh, my bad. Haven't been using git bisect for quiet a while and forgot to rate.
Ok, so I did bisect again

$ git bisect bad
7333ed1788b4f2b162a35003044d77a716732a1f is the first bad commit
commit 7333ed1788b4f2b162a35003044d77a716732a1f
Author: René Scharfe <l.s.r@web.de>
Date:   Mon Jul 28 20:26:40 2014 +0200

    setup: convert setup_git_directory_gently_1 et al. to strbuf
    
    Convert setup_git_directory_gently_1() and its helper functions
    setup_explicit_git_dir(), setup_discovered_git_dir() and
    setup_bare_git_dir() to use a struct strbuf to hold the current working
    directory.  Replacing the PATH_MAX-sized buffer used before removes a
    path length limition on some file systems.  The functions are converted
    all in one go because they all read and write the variable cwd.
