| Summary | 0002134: Incorrect asert logic in BaseVector<T>::Append | ||||
| Description | Hi guys, I've just been given an assert to look into. It's triggered on the following line: template<typename T> inline void BaseVector<T>::Append(const T* first, const T* last) { NS_ASSERT(last < Begin() || first >= End()); // <<<< HERE The end of the callstack is here: > Game.exe!Noesis::BaseVector<unsigned char>::Append(const unsigned char * first, const unsigned char * last) Line 434 C++ Symbols loaded. Game.exe!Noesis::VGL::AddSVGPath(Noesis::VGLPath * p, const Noesis::SVGPath & path) Line 220 C++ Symbols loaded. Game.exe!Noesis::GeometryProxy::GetPath() Line 44 C++ Symbols loaded. T* first 0x0000000148240080 "\x2" const unsigned char * T* last 0x0000000148240100 "\x2" const unsigned char * Vector<T>::mBegin 0x0000000148240100 void * So the SVG path contains 128 bytes worth of data from address 0x148240080 -> 0x148240100, and the address for the vector's heap allocated data starts at the last address 0x1482040100. This is perfectly valid from what I can see, it's just that both address spaces are contiguous and the SVG path is just before the path's data in memory. I think the asserts need to be last <= Begin, i.e: NS_ASSERT(last <= Begin() || first >= End()); Cheers, -Steven | ||||
