>Description:
g++-3.4 segfaults on code below:
$ g++ x.cc
x.cc: In member function `void ObjectSlot0_<Obj>::create()':
x.cc:6: internal compiler error: Segmentation fault
Please submit a full bug report,...
Interesting: if i change the 'new T ()' to 'new char[3]', i get a segfault, too, but with a different
message:
$ g++ x.cc
x.cc: In member function `void ObjectSlot0_<Obj>::create()':
x.cc:6: internal compiler error: tree check: expected class 't', have 'x' (
tree_list) in cp_parser_dependent_type_p, at cp/parser.c:1859
Please submit a full bug report,...
the latter is a parser error, the former makes not clear where it comes from. Should this
be two different bug-reports?
This bug is new with gcc-3.4 (does not happen with 3.3 & older)
>How-To-Repeat:
x.cc:
struct T;
T* manage(T* t);
template <class Obj> struct ObjectSlot0_ {
void create() {
void* tmp = manage(new T());
}
};
