Hmm. In system.c we have

    case SA_SAVE:
	if(runLast) R_dot_Last();
	if(R_DirtyImage) R_SaveGlobalEnv();
#ifdef HAVE_LIBREADLINE
#ifdef HAVE_READLINE_HISTORY_H
	if(R_Interactive && UsingReadline)
	    stifle_history(R_HistorySize);
	write_history(R_HistoryFile);
#endif
#endif
	break;


This looks wrong to me since write_history is getting called even if
!R_Interactive and !UsingReadline, in which case I don't think there
*is* a history to write and I'd suspect that anything could happen...
Could you try making that

        if(R_Interactive && UsingReadline) {
            stifle_history(R_HistorySize);
            write_history(R_HistoryFile);
	}
