std::_Rb_tree_const_iteratoraccess. - Weird pointer addresses in the
_M_nodedata structure.
When I ran TSAN, no such issue occurred (global place stage finished successfully). No error report by TSAN.
ASAN & UBSAN couldn't reproduce the issue (finished successfully without crash). No ASAN/UBSAN error report.
network_->drivers() returns a cached PinSet*. But the cache can be invalidated by the repairDriver() call in the loop, which can delete the drivers memory.
Thus, the drivers should be copied before the iteration.
