Bug#1099046: Acknowledgement (openMM: internal compiler error: in vect_get_vec_defs_for_operand, at tree-vect-stmts.cc:1509)
ccSEyJuT.out is attached generated after adding "-freport-bug"
to build/platforms/cuda/sharedTarget/CMakeFiles/OpenMMCUDA.dir/flags.make file
initial value:
CXX_FLAGS = -I/d12/shared/cuda/12.8.0_570.86.10/include -O2 -DNDEBUG -fPIC -msse2 -DLEPTON_USE_JIT -DOPENMM_COMMON_BUILDING_SHARED_LIBRARY -std=gnu++11
changed into:
CXX_FLAGS = -I/d12/shared/cuda/12.8.0_570.86.10/include -O2 -DNDEBUG -fPIC -msse2 -DLEPTON_USE_JIT -DOPENMM_COMMON_BUILDING_SHARED_LIBRARY -std=gnu++11 -freport-bug

Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-12/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccSEyJuT.out file, please attach this to your bugreport.
```
Other data points:
1) lowering the optimisation from -O3 to -O2 avoids the internal compiler error
2) using gcc-11/g++-11 (with -O3) instead og gcc-12/g++-12 does not cause any issue.
Best regards
