--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
```
#include <stdio.h>

[[gnu::noipa, gnu::noinline]]
void do_something()
{
        throw 1;
}

void bar(){
    []() noexcept{
    do_something();
    }();
}

int main()
{
        try {
        bar();
        }catch(...) { printf("incorrectly caught eh.\n"); }
}
```
Works as expected and std::terminate gets called.
I don't see a reason to directly call std::terminate here if it is going to=
 be
called from the personality function.

The original issue where this would be an issue was fix a while back. Anywa=
ys
at -O1 tail calls are not enabled even so you can't run into the original
issue.

See PR 82081 also.=
