[Bug c++/20357] New: Multiply defined assembler symbols for template instantiations

2005-03-07 Thread heinlein at informatik dot uni-ulm dot de 
The following code produces the assembler message: 
"Error: symbol `_ZN1XIXadL_Z1fvEEEC1Ev' is already defined". 
If the declaration of f in main is omitted, everything is fine. 
 
typedef void (*Func) (); 
template  
struct X { X () {} }; 
void f () {} 
X x; 
int main () { 
  void f (); 
  X x; 
}

[Bug c++/29645] New: undefined references to static const int members

2006-10-30 Thread heinlein at informatik dot uni-ulm dot de 
Compilation of the program below produces:
/tmp/cclEBTTX.o(.gnu.linkonce.t._ZN1XC1Eb+0x1a): In function
`X::X[in-charge](bool)':
: undefined reference to `X::a'
/tmp/cclEBTTX.o(.gnu.linkonce.t._ZN1XC1Eb+0x24): In function
`X::X[in-charge](bool)':
: undefined reference to `X::b'
collect2: ld returned 1 exit status

struct X {
static const int a = 1, b = 2;
int x;
X (bool f) : x(f ? a : b) {}
};
X x(true);
int main () {}

Replacing e. g. "a" with "a+0" makes the errors disappear.
