Dear all,
I would like to post a bug report for the GNU C/C++ compiler 3.3-e500.
We use the compiler to generate code for a PowerPC processor.
Used invokation line for the GNU C++ compiler:
ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
-fmerge-templates -mmultiple -mno-string -mstrict-align -O3
-fno-exceptions -fno-rtti -fno-builtin-printf
-I<some include paths>
-D<some #define's>
X.CPP -oX.O
// file X.CPP
template <typename, typename> class XXX;
template <typename, bool> struct enaFunc;
template <typename T_>
struct enaFunc<T_,true>
{ typedef T_ type; };
template <typename T_>
struct enaFunc<T_,false>
{};
template <typename T_>
struct isXXX
{
typedef char NO;
typedef char YES[2];
template <typename U_, typename V_>
static YES& check (const XXX<U_,V_>*);
static NO& check (...);
enum { value = (sizeof(check(static_cast<T_*>(0))) == sizeof(YES)) };
};
template <typename V_, typename U1_, typename U2_>
typename enaFunc<typename V_::T_RET_TYPE,
(isXXX<U1_>::value && isXXX<U2_>::value)
>::type
func (V_&, U1_&, U2_&); // function #1
template <typename V_, typename U1_, typename U2_>
typename enaFunc<typename V_::T_RET_TYPE,
(isXXX<U1_>::value && isXXX<U2_>::value)
>::type
func (const V_&, U1_&, U2_&); // function #2
struct YYY
{ typedef int T_RET_TYPE; };
void f (const XXX<int,char>& p1, const XXX<bool,int>& p2)
{
const YYY f = YYY();
func (f, p1, p2); // <--- line 49
}
The compiler crashes with the following message:
X.CPP: In function `void f(const XXX<int, char>&, const XXX<bool, int>&)':
X.CPP:49: internal compiler error: Segmentation fault
(Comeau online compiles the code fragment fine.)
Kind regards
W. Roehrl
