A recent change required knitr to actually tangle the code for
vignettes when requested by R CMD check, with the intent to make sure
that the resulting *.R file runs without errors. Unfortunately, chunks
with error = TRUE get included in the tangled output, but it's not so
simple to fix for historical reasons, partially because a simple tangle
would not work for vignettes that expect to interact with the
vignette engine from inside their code chunks or rely on the side
effects from inline expressions.

Tim Taylor has very helpfully provided [*] the link to the knitr issue
with more context: https://github.com/yihui/knitr/issues/2338

purl=FALSE should indeed work; see
https://github.com/yihui/knitr/pull/2036 and

context.
