The `record_map` accesses in `__kmp_track_dependence` are not protected for a concurrent reallocation of the vector. I didn't check all the other accesses to the `record_map`, whether they might be concurrent to a reallocation.

I think there are two options: 
- lock any access to `record_map` that is possibly concurrent to a write/push (probably way too expensive)
- store a pointer to the node_info in kmp_taskdata_t: `task->tdg_node_info = task->tdg->record_map[task->td_tdg_task_id]`
