...static instance_ = 0x7fff13d42d10} since there's no function called stringConcatfactoryrandom in my R code, the above call fails. The I use the same R instance to call R.parseEval("exists") and I get this (gdb) p R $8 = (RInside &) @0x7fff13d42d10: {mb_m = {buffer = "stringConcatfactoryrandomexists"}, global_env = <incomplete type>, verbose_m = false, static instance_ = 0x7fff13d42d10} I think the buffer should be cleared after each call to parseEval Thanks Pratibha
