Do you have any idea under what circumstances this happens.

This has been reported before. I am still seeing it with R-3.2.3.
It appears randomly. It sounds scary.

FWIW, I can reproducibly get CGContext* errors by running R in a
terminal window, plotting something (for example `example(hclust)' and
answering RET to the prompts), then hitting the maximize (green)
button on the graphics window. However, these messages do not produce
the `fatal error' threats mentioned in Rich's email.
I can report the output from doing this under
`CG_CONTEXT_SHOW_BACKTRACE=yes R' if that helps.
