AMD Segmentation fault

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.

Reproduce the crash with the provided dem2mesh command and large dataset, then investigate the edge-collapse phase where processing stops. Use a debugger to compare behavior on AMD and Intel environments. Done means the dataset processes without a segmentation fault and the AMD-specific failure is covered by a repeatable verification.
