<pre>$ cat main.cpp
```
#include <iostream>
int main(int argc, char** argv) {
std::cout << "hi c++ from jit: " << argv[0] << std::endl;
return 0;
}
```
Compile with 'no-use-cxa-atexit'
$ clang++ -S -emit-llvm main.cpp -stdlib=libstdc++ -fno-use-cxa-atexit
the 'main.ll' load fine with lli 'orc-mcjit' and 'mcjit'
$ lli --jit-kind=orc-mcjit ./main.ll
hi c++ from jit: ./main.ll
$lli --jit-kind=mcjit ./main.ll
hi c++ from jit: ./main.ll
while with orc-lazy, I get undefined symbol
$lli --jit-kind=orc-lazy ./main.ll
JIT session error: Symbols not found: [ atexit ]
JIT session error: Failed to materialize symbols: { (0x23e0c50, {
__orc_lcl.__cxx_global_var_init.0, _GLOBAL__sub_I_main.cpp }) }
The issue can be found on both clang10 and clang11.</pre>
