Ichthyostega aac9ee2934 Bugfix: uninitialised stack-memory used in test ...

...this bug was spotted as the test failed reproducibly
when built with `-fstack-protector-strong` — which adds
additional "canary" markers to some kinds of problematic
stack storage; this seemed to have the effect that now
the second test uses exactly the same location as the
preceding test, and thus finds valid data in the newly
created work buffers.

There is no reason for using uninitialised storage in this
test (I can recall that I wanted to build a generic helper
and intended to use that as ''virtual overlay'' over existing
memory — but that usage never took place, and the `struct Buffer`
is not a general-purpose tool now, but only made for this
specific test. Thus memory can be easily zero-initialised.
