Segmentation Fault from DDECAL

[a-benati]

Hi all,

I get a segmentation fault after launching DP3 6.0.0 on my data, for which I want solutions in 4 different directions. The DP3 command is the following (it is launched from within loafer_facetselfcal, therefore some parameters are set by default and not by me):

DP3 numthreads=64 msin=1685906777_sdp_l0-Abell3667-corr_avg.ms.copy msout=. ddecal.mode=sc
alarphase msin.weightcolumn=WEIGHT_SPECTRUM steps=[ddecal] ddecal.type=ddecal msout.storagemanager=dy

 ddecal.smoothnessspectralexponent=-1.0 ddecal.smoothnessrefdistance=0.0 ddecal.tolerance=0.0001

And this is the output:
