Segmentation fault running some correlation function tests

[evevkovacs]

Trying to run some correlation function tests generates a seg. fault. Here is an example.
This has happened since the update to treecorr. The error happens for both proto-dc2 and cosmoDC2 runs using the master branch of descqa. I have successfully run other tests today, so I think the  problem is specific to this test. I have also run another part of this
correlation  function test today (the tpcf_Wang2013_rSDSS test which is the angular correlation function test, so is not exactly the same code). That run was successful.
Here is the traceback:

Preliminary investigation suggests that the Segmentation fault takes place during this function: https://github.com/LSSTDESC/descqa/blob/master/descqa/CorrelationsTwoPoint.py#L314

But still need to look into details of which specific line of treecorr causes this.

I just confirmed that ./run_master.sh -c proto-dc2_v5.0 -t tpcf_Zehavi2011_rSDSS also generates the seg. fault. So both classes CorrelationsProjectedTwoPoint and DEEP2StellarMassTwoPoint generate the error while CorrelationsAngularTwoPoint does not.
