Problems with embedded R, ReplDLL
...es given of embedded R use.
One problem can be seen in R_ReplDLLinit, in src/main/main.c:
void R_ReplDLLinit(void)
{
SETJMP(R_Toplevel.cjmpbuf);
R_GlobalContext = R_ToplevelContext = R_SessionContext = &R_Toplevel;
R_IoBufferWriteReset(&R_ConsoleIob);
prompt_type = 1;
DLLbuf[0] = DLLbuf[CONSOLE_BUFFER_SIZE] = '\0';
DLLbufp = DLLbuf;
}
The call of SETJMP makes no sense. Nothing that follows in this
function can possibly cause a long jump. The use of R_ReplDLLinit is
illustrated in the R Extensions manual (doc/manual/R-exts.texi):
