[R-SIG-Mac] Error message when folding code

[Gabriel Henrique de Oliveira Caetano]

Hi! I get the following error message sometimes when I try to fold { } brackets in the script editor at the standard mac GUI. I don’t see any pattern it sometimes happen and sometimes doesn’t, and the only common thing is folding the brackets. If this happens many times, R eventually crashes. I tried reinstalling R and the problem persists. What can I do to avoid this?
