Disable failing testcase

This commit fed5a41fb1c2c91b77297fdd6d3731078f480441 introduced the concat
builtin macro but the error handling here is producing an infinite loop
which was not caught during code-review. This patch disables the offending
error cases so that it does not impact further development.
