Documentation for tests/osaka/eip7692_eof_v1/eip663_dupn_swapn_exchange/test_swapn.py::test_swapn_stack_underflow@3719e927.

Generate fixtures for these test cases for Osaka with:

fill -v tests/osaka/eip7692_eof_v1/eip663_dupn_swapn_exchange/test_swapn.py::test_swapn_stack_underflow --fork Osaka

Test case out of bounds SWAPN (underflow).
