Hi,
The problem is better illustrated with:
library(inline)
test2 <- cfunction(body = '
SEXP success = PROTECT(ScalarLogical(0));
setAttrib(success, install("foo"), mkString("bar"));
UNPROTECT(1);
return success;
')
test3 <- cfunction(body = '
SEXP success = PROTECT(S

I believe this is by design (and changed relatively recently). FALSE and
TRUE are singletons, like NULL.
