Obviously the following code of the definition of class destructor is wrong,
but it passed g++ 4.4.2 in Fedora 12. However g++ 4.1.2 and g++ 3.4.6 in Fedora
12 reported the error.
The testing code is list below:
#include
template
class Base
{
public:
Base();
~Base();

Oh and the most likely reason is that why Fortran fails and C works is because
libgfortran weakly imports some pthread symbols which causes the pthread static
library not to be fully included.

I'm curious why this problem only appears for Fortran code and not for C. If it

of inline functions is e.g. debugging, if there is no out of line copy of a
