:wave: Hey,
Under some test case layouts the call relocation panicking with an underflow. Use
wrapping_subto signal that this is expected.The fuzzer took a while to generate such a test case. And I can't introduce it as a regression test because when running via the regular clif-util run tests the layout is different and the test case passes!
I think this is because in the fuzzer we only add one trampoline, while in clif-util we build trampolines for each function in the file.
