Bug ID: 110107
Summary: ICE on invalid code with lambda
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: stevenxia990430 at gmail dot com
Target Milestone: ---
The following invalid program produces internal compiler error: error reporting
routines re-entered. Tested on GCC-trunk. Apologies that it might be complex, I
had a hard time trying to reduce the small code snippet.
To quickly reproduce: https://gcc.godbolt.org/z/rdfvaEbP5
```
#include <utility>
using namespace std;
template <class T>
auto make_safe(T lambda) -> decltype([](auto&&... args){return
lambda(args...);})
{
try
{
return [lambda = std::forward<T>(lambda)](auto&&... args) ->
decltype(lambda(args...)){ return
lambda(std::forward<decltype(args)>(args)...); };
}
catch(...){}
}
int main()
{
auto safef = make_safe([]()
{
return 0;
});
return 0;
}
```
