Hello,
I was trying to use lli to run a very simple c++ program on linux that uses the
c++ library but the interpreter crashed. But the same works fine with JIT
enabled. I am wondering if anyone has encountered similar issues?
Thanks,
Alvin

Hello> (fyi lli was trying to invoke the dtor std::basic_string<char, > std::char_traits<char>, std::allocator<char> >::~basic_string() when > it choked)Interpreter tried to execute external function, but failed, since this function is not known to interpreter. In general, interpreter does not support calling external functions. --- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University
