Compilation failure in absl/container/internal/inlined_vector.h with NVCC

[suryakiran]

Describe the bug

When including absl/container/flat_hash_set.h in a cuda source file and compiling the source file with nvcc (11.4.1) and gcc (9.3.0), the compilation fails with the following error.

Steps to reproduce the bug

Include absl/container/flat_hash_set.h in a cuda source file and compile with nvcc. Attached CMakeLists.txt, test.cpp (as test.cpp.txt) and test.cu (as test.cu.txt) to reproduce the problem.

I get the same error

[derekmauro]

I'm guessing the reason TensorFlow has this patch https://github.com/tensorflow/tensorflow/blob/da83132aba8d2b6a3c3a9b2e662868eb24f4dd1e/third_party/absl/com_google_absl_fix_mac_and_nvcc_build.patch#L243-L256 is to deal with this issue.

I'm not setup with the compiler you are using, but if someone could verify that this fixes the issue I will patch our code.

[suryakiran]

This patch is working.

[derekmauro]

Thank you for confirming. A patch is coming.

[derekmauro]

Fixed in 5202173.

[suryakiran]

Thanks much for the fix. I'd like to know if there is any patch for the LTS coming up or should I use the master ?

[derekmauro]

This won't be patched in the LTS. We actually recommend living at head and updating frequently.

[suryakiran]

Thanks for the confirmation. And once again, thank you for the patch. I'll use the master.
