At the same time copying to the clipboard does no longer work with "out of memory" error (i.e. when trying to copy the error message from grep to this msg.) Also breaks other functions (regexpr, strsplit) that seems to use the regex functions internally. Things work again after restarting R.
Looks like a memory/resource leak. Can you send us an actual failing example on your machine, starting from a clean session, together with details of the machine (amount of RAM etc)? That will help us greatly to reproduce this.
