Details
I was trying to get Gaia running on my desktop this morning but failed. Compared to bug 740028 & bug 732467, it was also a segmentation fault right before b2g homescreen is shown. However, the root cause is different. I used gdb and traced the code, found that the error occured at Ril.cpp. To be precise, it occured at the first line of the function RilReconnectTask::Run(), sClient->OpenSocket(), sClient was null then. I've checked source code with Cervantes and found that sClient would be cleared to nsnull in StopRil(), which is called by SystemWorkerManager::ShutDown(). That might get into a race condition because sClient is initialized in ConnectToRil(), then a new runnable would be dispatched to IOThread by calling sClient->mIOLoop->PostTask(FROM_HERE, new RilReconnectTask()); Moreover, this task would be posted again every time if sClient->OpenSocket() returned false. During this re-posting period of time, once SystemWorkerManager::ShutDown() is called, this error will occur.
