<div>Hi,</div>
<div> </div>
<div>When using MatMatSolve with superlu_dist I get a segmentation fault:</div>
<div> </div>
<div>Malloc fails for lsum[]. at line 1075 in file /home/petsc3.14.release/arch-linux-c-debug/externalpackages/git.superlu_dist/SRC/pzgstrs.c</div>
<div> </div>
<div>The matrix size is not particular big and I am using the petsc release branch and superlu_dist is v6.3.0 I think.</div>
<div> </div>
<div>Best,</div>
<div>Marius</div>
