Package: g++-4.3
Version: 4.3.0-5
Severity: normal
*** Please type your report below this line ***
I've found a problem with g++-4.3 (also tested with current snapshot
package), I'll describe it using this testing source code:
[CODE STARTS] file bug.cc
class BUG
{
public:
bool name() { return true; }
};
template <bool T>
struct BUG1_5
{
};
template <bool name>
class BUG2 : BUG
{
public:
typedef BUG1_5<name> ptr;
};
int main()
{
BUG2<false> b;
return 0;
}
[CODE ENDS]
Compiling with "g++ -save-temps bug.cc -o bug" causes:
[OUTPUT STARTS]
bug.cc:17: internal compiler error: Naruszenie ochrony pamięci
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.3/README.Bugs> for instructions.
[OUTPUT ENDS]
(`Naruszenie ochrony pamięci' means `Segmentation fault')
Crash appears when there is class template with same parameter name as
parent's function and same parameter type as that function's return type
and then we e.g. typedef some with this parameter. There are also
problems when template parameter has same name as parent's function (but
different parameter type), but they don't crash.
