Hi All, I'm new at this forum. I encounter problem with circular_buffer. Let me explain it on simple example (code is from circular_buffer.h): I have a circular_buffer with few elements . After read one of them element is destroyed: template < typename T > T circular_buffer<T>::read() { T t = read_data(); buf_clear( m_buf, m_ri ); increment_read_pos(); return t; } template < typename T > inline void circular_buffer<T>::buf_clear( void* buf, int n ) { (static_cast<T*>(buf) + n)->~T(); } } // namespace tlm ... but In dectructor all elements are destroyed ... again template < typename T > circular_buffer<T>::~circular_buffer() { for( int i=0; i < used(); i++ ) { buf_clear( m_buf, i ); //!!!! } buf_free( m_buf ); } This case GPF's randomly. I notice that when I change desctructor code to for( int i=m_ri; i < used() % m_size; i++ ) { problem disappears I'm using SystemC 2.3.0 Is this a bug in TLM sources or I'm doing something wrong ?
