Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
The above is with gcc-4.0.0, but the identical happends with
gcc-3.4.3 and 4.1.0 20050702 (experimental). The code follows:
--------------------------------bug02.cc-----------------------------
template<typename T, int M>
void do_something( const T A[M][M])
{
struct helper_t{
helper_t():B(new double [M*M]){
B[0] = A[0][0];
}
~helper_t(){ delete[] B; }
double * B;
} helper;
}
void sub1()
{
double A[3][3];
do_something(A);
}
-----------------------------end bug02.cc-----------------------------
As always, thank you. You folks do excellent work.
Sincerely,
Mike Albert
