The following code produces a situation where the CPU usage reaches 100% and devenv does not accept any commands - not even "after a while". To reproduce the problem, please open any existing solution that contains a C++ project with VS .NET 2003, create a new C++ header file and paste the following code. After some seconds (3 s on my P4 2.4 GHz single-CPU), the deadlock occurs.
template <class PARENT, class THISARG>
class B : public PARENT {
public:
typedef PARENT Parent;
typedef THISARG ThisArg;
};
template <class THISARG>
class N : public THISARG {};
template <class THISCLASS, int Nest>
class A : public A<typename THISCLASS::Parent, Nest - 1> {};
template <class THISCLASS>
class A<0> : public N<typename THISCLASS::ThisArg> {};
Note that the problem does not occur if a new header file is created with no solution loaded. Also, the following code works fine:
class N {};
template <int Nest>
class A : public A<Nest - 1> {};
template <>
class A<0> : public N {};
Is there any chance that VA gets modified in such a way that the coloring thread (or whatever causes this deadlock) never ever has the chance to deadlock or even slow down the whole IDE? Colors are fine, but stability comes first for me. I like VA very much, and this is already the second problem that forced me to turn it off :-(
