InvalidProgramException while expression compilation with C++/CLI field #118837
Description
Description
Since .NET 10.0.0-preview.7.25380.108 the compilation of the following expression fails with a InvalidProgramException.
Reproduction Steps
.NET 10.0.0-preview.7.25380.108 x86 Release - Console Application
System.Linq.Expressions.Expression<Func<CSharpClass>> expression = () => new CSharpClass();
expression.Compile();public class CSharpClass
{
private CppClass _field = new();
}.NET 10.0.0-preview.7.25380.108 x86 Release - C++/CLI Library
public ref class CppBase abstract
{
public:
~CppBase() {}
!CppBase() { _pValue = nullptr; }
protected:
void* _pValue;
};
public ref class CppClass : public CppBase
{
public:
CppClass() { _pValue = new int(); }
};Expected behavior
The Compile method returns the compiled expression.
Actual behavior
The Compile method throws a InvalidProgramException.
System.InvalidProgramException: Common Language Runtime detected an invalid program.

Regression?
The exception occurs since .NET 10.0.0-preview.7.25380.108.
Known Workarounds
When disabling the inlining of the constructor the error does not occur.
public class CSharpClass
{
private CppClass _field;
[System.Runtime.CompilerServices.MethodImpl(System.Runtime.CompilerServices.MethodImplOptions.NoInlining)]
public CSharpClass()
{
_field = new();
}
