Let me know, @mramospe and @franciscosili, if this PR fixes the issue in your context. As you can see above, I wasn't able to reproduce it.

I can't reproduce with your test, but this one works for me

import ROOT


def test_import():
    h = ROOT.TProfile3D()
    __import__("uproot").from_pyroot(h)

I verified that TProfile3D raises a segfault in main (whereas TH1F does not), but it's fixed in this PR. I wonder what's special about TProfile3D—maybe there's a new class version for it? Or maybe we don't have predefined streamers for it?

uproot5/src/uproot/behaviors/TH3.py

Lines 4 to 5 in a8644df

	This module defines the behaviors of ``TH3`` and its subclasses (not including
	``TProfile3D``).

Well, this does verify that there's a segfault without the fix and no segfault with the fix, so I'll ask @ioanaif to review this PR and merge it if everything's good. (I'm not planning on making any more changes.)

LGTM!

Works for me now. Thanks a lot!

The test for this now breaks; see issue #1237.
