* Fix non-CUDA Thrust handling of __host__/__device__ * Add some missing headers in the Thrust CPU backends. * Remove unused variables. * Add missing header. * Move deprecation markup to `result_of` definition. Having the deprecation markup on the declaration instead of the definition cause the deprecation diagnostics to be emitted when defining the deprecate type on gcc. Moving the markup fixes this. * Don't expose builtins as functions in thrust. error: use of built-in trait '__is_same(..., ...)' in function signature; use library traits instead. * Remove re-declaration of `reference_wrapper` This type was already forward-declared in `is_reference_wrapper.h`. Redeclaring it with the vis attribute broke gcc. * Disable failing OpenMP test (tracked in #1715). * Print CMake configure step on windows. * Use installed TBB CMake configs if available. Fallback to our FindTBB.cmake as a last resort.

Type of Bug
Runtime Error
Component
Thrust
Describe the bug
Running the
thrust.cpp.omp.cpp17.test.unique_by_keytest with either theTestUniqueCopyByKeyLargeInputorTestUniqueCopyByKeyLargeOutputtest cases enabled results in a runtime fails. No exception is thrown, no error emitted, the process just prints "Killed" and exits.This was noticed on gcc-12 + nvcc-12.4.
These two test cases will be disabled by #1696 until this can be investigated.
How to Reproduce
Build and run all
cpp.omptests using the cuda12.4-gcc12 devcontainer.Expected behavior
The test should pass.
