// icpx ICE on illegal code in HandleDestructionImpl

[vzecca]

The following illegal code provokes an ICE in icpx Version 2021.1 NextGen Beta Build 20200304

Even though the code is illegal the compiler should not crash but give a meaningful error message and end quietly.

// icpx ICE on illegal code in HandleDestructionImpl
union b; // this is illegal

struct S {
template <typename>
void a()
try {
} catch (int ()
noexcept (({ union b a; true; })))
{
}
};

Hi,

On compiling your code snippet with the latest build, I could see the following error messages.

bug_union.cpp:8:22: error: variable has incomplete type
      'union b'
noexcept (({ union b a; true; })))
                     ^
bug_union.cpp:1:7: note: forward declaration of 'b'
union b; // this is illegal
      ^
1 error generated.
compilation aborted for bug_union.cpp (code 1)

Looks like this issue is fixed in the latest ICPX build (icpx (ICX) 2021.1 Beta 20200715).

Could you upgrade to the latest build and try?

Thanks,

Rahul
