Enter the following at the R command prompt:

sprintf("A %S %S %S XYZ", 1, 1, 1);

Note the erroneous capitalized %S instead of %s and the numeric inputs instead
of strings. With strings there's no crash - R reports bad format
specifications.

2.7.2 is obsolete, but I can confirm a crash on Windows with a recent 
R-devel.

Can confirm as well on OSX with a fairly recent R-devel.
