Segmentation Fault in get_tet_euler when running VolumeVoronoiGPU #1
Description
I encountered a Segmentation Fault when running ./bin/VolumeVoronoiGPU with a .msh file generated by fTetWild. The program crashes immediately after loading the mesh.
Environment
OS: Ubuntu 22.04 (WSL2)
Mesh Input: .msh format (generated by fTetWild)
Steps to Reproduce
Run the following command:
./bin/VolumeVoronoiGPU -i /path/to/mesh.msh -oGDB Debug Output
Here is the backtrace captured by GDB, showing the crash occurs in extern/libmat/src/IO/IO_CXX/io.cxx:
