>Description:
gcc 3.1 rejects the following code tp.C extracted from
libs/pool/test/test_pool_alloc.cpp from the current boost
repository. gcc 3.01 and gcc 2.95.2 accept this code.
>How-To-Repeat:
Source code tp.C
template <unsigned I> struct A {};
template <typename SizeType>
struct B
{
char * f() const
{
return (A<sizeof(void *)>::value);
}
};
