PoissonReconClient segfault with --multi 32 and default --pDepth 5

[nh2]

Are there some unenforced requirements on the sizes of --multi and --pDepth?

I notice that --multi 32 --pDepth 5 crashes with a segfault, but the problem goes away with --multi 32 --pDepth 6.

--multi 31 also crashes, --multi 30 does not.

Details:

Bin/Linux/PoissonReconServer --in cloud.ply --out niklas-mesh-2.ply --verbose 3 --density --depth 8 --samplesPerNode 1 --parallel 3 --tempDir ~/tmp/niklas-poisson-server-tmp2 --port 1234 --count 32

Bin/Linux/PoissonReconClient --port 1234 --parallel 3 --multi 32 --localTempDir /tmp/niklas-tmp2
