Crash after including cpp11 headers

[krlmlr]

This PR is based on a state before we used the cpp11 package.

The first commit adds a test script. The second commit includes a single file from cpp11 and leads to a segmentation fault in the test script. Why?

Downstream issue: dm tests on my machine not stopping (or segfaulting) for the RSQLite variant.

The backtrace in the debugger shows an interaction between duckdb and RSQLite that I can't quite fully grasp:

@Antonov548: Can you please take a look? What other info do you need?

This only seems to happen on macOS arm64, I don't see the failure in a Linux container.
