Hello everybody,
today, I noticed a bug in gcc 4.4.0. The compiler segfaulted during
the compilation process. I also tested the same code with gcc 4.3.3, which
works perfectly fine.
I narrowed it down to the following test program:
------------------------------------------------
template <typename T> class test
{
private:
int num_bins;
public:
void testing(void);
};
template <typename T> void test<T>::testing(void)
{
double jackdata[this->num_bins];
}
int main()
{
test<double> t;
t.testing();
}
-----------------------------------------------
The compilation command line is:
g++ test.cc
Error output:
test.cc: In member function void test<T>::testing() [with T = double]:
test.cc:17: instantiated from here
test.cc:10: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
