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2.7.2 is obsolete, but I can confirm a crash on Windows with a recent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.
The last few entries in the stack dump at the time of the crash are
shown below; these make it look as though the problem is in the Trio
library, so it may be hard to fix.
