[Rd] Memory leak possible when redirecting R console

Hello,

To trigger the memory leak, an application embedding R will have printed   a vector element of size R_BUFSIZE or more to stdout, so long as the R_Outputfile pointer is NULL and R was compiled with vasprintf support. The leak is in Rcons_vprintf from printutils.c. It looks as though someone set up a fix for this but forgot a critical flag assignment when vasprintf() is called (vasprintf mallocs a buffer to print to, so it needs to be freed after use). Here's the fix:

Index: printutils.c


Best,

Jeff
