ASSERT_*() is supposed to exit the test right away. If this isn't happening it needs to be debugged.

We know it doesn't work in setup/teardown functions, you can see it in the code it jumps back and does the teardown again in an infinite loop.

If mising assert and ASSERT causes loops that is also a bug, we can't guarentee that no libraries linked into this (like glibc) doesn't call assert.
