Hi, I've been trying to run the connected components application provided by Galois (both local CPU and distributed CPU) and cannot seem to get correct results unless I use the Serial implementation.
I ran the standard CMake setup using the release-6.0 branch, with a few small hiccups
Had to add #include <optional> in graph-convert
Additionally, got an error about a constexpr in lonestar/scientific/cpu/longestedge/test/catch.hpp:10735:58 which I hacked around since I don't think it should affect anything else

Any help would be greatly appreciated. I have attached the input files (both .mtx and .gr formats). Note that I have locally verified the correctness of the graph format conversion by round-tripping then running a simple isomorphism check. I've tried a few graphs with no success so I doubt the specific input matters.
I am happy to provide any system information or build output as needed, thanks!
