<pre>On arm64-apple-darwin20.3.0, consider the following code:
% cat test.cc
int main() {
try {
throw 1;
} catch (...) { }
}
When compiled into an executable (by either Apple clang or Clang trunk), the
program exits normally:
% clang++ -O2 throw.cc -o throw
% ./throw
% echo $?
0
However, the same code crashes when compiling into LLVM IR and executing via
lli:
% clang++ -O2 -S -emit-llvm throw.cc
% lli throw.ll
libc++abi.dylib: terminating with uncaught exception of type int
I've tried all combinations of --jit-kind and --jit-link, none of them worked.</pre>
