make test failed with AutogradTest etc.

I build with "cmake .. -DCMAKE_BUILD_TYPE=Release -DFLASHLIGHT_BACKEND=CPU"
after making, I make test, unfortunately, I got many failed items, the logs as follow:

45% tests passed, 6 tests failed out of 11

Total Test time (real) = 75.65 sec

The following tests FAILED:
1 - AutogradTest (Failed)
2 - OptimTest (Failed)
3 - ModuleTest (Failed)
4 - SerializationTest (Failed)
9 - AllReduceTest (OTHER_FAULT)
10 - ContribModuleTest (Failed)
Errors while running CTest
Makefile:71: recipe for target 'test' failed

But I didn't find any abnormal information when configuring and making, could anyone help me fix it?

When I run ./AutogradTest in ./build/test directory, I got the trace information as follow, which looks like related to CPU backend.
