There's nothing Qt-related in the backtrace. You could start by compiling OpenCL (and whatever purestudio is) with debugging symbols so the backtrace is more informative.

Thanks Chris,

OpenCL is not my DLL and I have no debug symbol ! PureStudio is mine and it has debug symbols... I' m able to debug the source code and even, the modules window (MSVC) says that symbols are loaded !

This stack is strange, really I don't know why I don't see my methods in this stack trace !
