Old Synopsis: typedefs in template class
New Synopsis: [3.2 regression] ICE with typedefs in template class
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Thu Feb 6 19:57:53 2003
State-Changed-Why:
Confirmed: ICEs with 3.2.*, works with 2.95, 3.3 and 3.4.
Here's a redux:
----------------------------
template<typename T> struct X {
typedef T* type();
type t;
};
template struct X<int>;
------------------------
tmp/g> /home/bangerth/bin/gcc-3.2.2-pre/bin/c++ -c x.cc
x.cc: In instantiation of `X<int>':
x.cc:5: instantiated from here
x.cc:3: internal error: Segmentation fault
Please submit a full bug report,
I am unsure about the validity of the code, in particular
typedef T* type();
I guess at the best this would qualify as a reference to
a function. Making this a pointer-to-function like
typedef T* (*type)();
makes the compilation go through. So I guess this is an
ICE-on-illegal.
