[R-SIG-Mac] Valgrind on Snow Leopard or Lion

[Ruth Ripley]

I have been tying to get valgrind to run on Snow Leopard and Lion 
without much success. I get reports of errors but the process tends to 
hang before exiting. It only terminates occasionally after an error. 
Thus I cannot get leak reports.

For example: if ls.r contains the one line: ls()

R -d "valgrind --tool=memcheck" --no-save < ls.r

will produce the following and hang

valgrind --tool=memcheck ls

works fine. So an R problem rather than a valgrind one, I fear.

Any help would be greatly appreciated.

Thanks,
