On AMD, while processing a particularly large dataset, I'm experiencing a segfault during the edge collapse phase. This doesn't appear to occur on intel.
Eg:
./dem2mesh -inputFile mesh_dsm.tif -outputFile odm_25dmesh.dirty.ply -maxTileLength 2000 -maxVertexCount 200000 -edgeSwapThreshold 0.15 -verbose
... snip ...
iteration 90 - triangles 5391543 threshold 6.95688
iteration 95 - triangles 4981377 threshold 9.03921
Performing edge collapses...
[1] 438838 segmentation fault (core dumped) ./dem2mesh -inputFile mesh_dsm.tif -outputFile odm_25dmesh.dirty.ply 2000
I'm experiencing this crash when using opendronemap/nodeodm image as well as building dem2mesh manually.
