  The freeing of the malloced memory is difficult when using asserts to
cause early abort of the test cases, since that can leak memory. The
original placement of the free call caused a memory leak if the test
finished early, while a fix for that leak caused the test to fail at
times due to the memory variable being referenced after free. For a case
like this, using stack rather than heap memory is just easier and avoids
all issues.
