blueos reducer reset test failure with gcc

[rhornung67]

The RAJA unit test 'test-reducer-reset-seq.exe' fails reliably when the code is built with gcc and nvcc (note: only sequential version). The same test passes with other host compilers. Any thoughts on this?

There is usually a missing compiler flag for this problem: #1073 (comment). Although @trws's reaction in that thread indicates that there may be a more serious problem with something being inlined out, in order for the test to work.

Thanks @rchen20 I forgot about that. I'll try adding that compiler option.

Do you have error output for when the test fails? I checked over in the other issue and can’t seem to find an instance of the failure in the azure logs.

I would have to rerun. This may have come up in CI discussion before (I can't recall) and the compiler flag @rchen20 referred to may have been added in the appropriate location. I'll do some more exploration with that option and report back.

I'll need to check, but I think in certain places the Gitlab CI files are missing that flag (which I thought I had fixed a while ago).
