int __fastcall TForm1::test() {
bool done = false;
int retval = 0;
try {
try {
retval = 1;
done = true;
}catch(...) { }
}
__finally {
ShowMessage("come1");

return retval;

try {
try {
retval = 2;
done = true;
}catch(...) { }

}
return retval;
}
void __fastcall TForm1::Button1Click(TObject *Sender) {
