hi all.. I'm getting an EXC_BAD_ACCESS at__TBB_MACHINE_DEFINE_ATOMICS(8,int64_t,"q")using the TBB40_20120408oss source release built as dynamic debug libs with XCode 4.3.2 using default settings (LLVM 3.1) on a Mac mini mid-2011 with i5 cores running Lion 10.7.3. The stack and project files are attached.. I've tried to keep the source as simple as I can without departing too far from the scenario that first caused the problem. It runs some concurrent_vector code through a pipeline. The exception occurs every time the code runs.. I suspect I'm probably breaking a fundamental rule somewhere, but haven't found anything obvious. Any help finding a workaround or fix would be appreciated. thanks!
