    clang++ version :16

bolt --version output:

>   LLVM version 16.0.0. DEBUG build with assertions. BOLT revision 08d094a0e457360ad8b94b017d2dc277e697ca76

 
reproduce demo

```
int Foo() { throw 42; }

int main() {
  try {
    return Foo();
  } catch (...) {
    return 0;
  }
}
```

when compile with -no-pie，after bolt optimization, it SIGSEGV when run the main.bolted. here is the build script:

>  clang++ main.cc -g -Wl,--emit-relocs -stdlib=libc++  -lc++abi -pthread -no-pie -o main
>  llvm-bolt  ./main -o main.bolted

Since programs compiled after llvm15 are compile with pie by default, here if I remove the no-pie option, the Bolt-optimized program will run without SEGV errors. 

I would like to know what caused the no-pie program SEGV. Thank you for your reply
