[R-SIG-Mac] [R] R.app GUI 1.40 predictably and repeatably freezing PPC ONLY

[Martin Ellis]

I've also noticed this behaviour on my PPC
(powerpc-apple-darwin9.8.0/ppc (32-bit)), and have reverted to 2.12.2
until I can figure out the problem. Since the command-line R seems
fine, I assumed the problem was with the R.app GUI too.

This does not seem to occur when running R from Terminal.app. The freezing seems associated with what should be simple syntax errors. All other features seem to be working expect "Show function hints" at the bottom of GUI is grey. All my "syntax error free" code seems to parse and run just fine via source() or cut and paste.
