t9128 failing randomly with svn 1.9?

While running tests for my object_id part 11 series, I noticed a random segfault in git svn while running t9128. I've reproduced this on a different machine as well, using both Subversion 1.9.5 and 1.9.7 (Debian stable and unstable). It is reproducible on master.

When the test fails, it fails on the "git svn tag tag3" step, and I get the following:

Copying file:///home/bmc/checkouts/git/t/trash%20directory.t9128-git-svn-cmd-branch/svnrepo/trunk at r2 to file:///home/bmc/checkouts/git/t/trash%20directory.t9128-git-svn-cmd-branch/svnrepo/tags/tag3... Found possible branch point: file:///home/bmc/checkouts/git/t/trash%20directory.t9128-git-svn-cmd-branch/svnrepo/trunk => file:///home/bmc/checkouts/git/t/trash%20directory.t9128-git-svn-cmd-branch/svnrepo/tags/tag3, 2 Found branch parent: (refs/remotes/origin/tags/tag3) 0604824a81a121ad05aaf8caea65d8ca8f86c018 Following parent with do_switch Successfully followed parent r7 = f8467f2cee3bcead03e84cb51cf44f467a87457d (refs/remotes/origin/tags/tag3) error: git-svn died of signal 11

Doing the following three times, I had two crashes.

(set -e; for i in $(seq 1 20); do (cd t && ./t9128-git-svn-cmd-branch.sh --verbose); done)

I'm not really familiar with git svn or its internals, and I didn't see anything recently on the list about this. Is this issue known?
