thanks for the answer. The patch improved the situation, but unfortunately
didn't solve the problem.
Before the patch, the InheritsFrom() method failed always.
After the patch the following happens:
root [0] using namespace TG
root [1] MyLeaf a
MyClass constructor
MyLeaf constructor
root [2] a.InheritsFrom(TObject::Class())
(const unsigned char)0
root [3] a.InheritsFrom(MyClass::Class())
(const unsigned char)1
root [4] a.InheritsFrom(TObject::Class())
(const unsigned char)1
The weired statement is [2]. The InheritsFrom() method fails
the first time, later it works.
What else has to be patched?
Goodbye,
Thorsten
