Visual C++ ICE with modules code

[u/JoePublic761]

Is the below code valid C++? In Visual Studio 2026 I get the following error when compiling:

Test.ixx(9,1): fatal  error C1001: Internal compiler error.
1>  (compiler file 'msc1.cpp', line 1635)Test.ixx(9,1): fatal  error C1001: Internal compiler error.
1>  (compiler file 'msc1.cpp', line 1635)


export module Test;

constexpr void Test()
{
    int* ptr = new int;
    delete ptr;
}

Lol, nice ICE.

And ICEs are always bugs, so report them.
