| // error, for example, when the stack/heap is badly damaged. We must be |
| // able to handle recursive errors that happen inside error handler. |
| // |
| // Error reporting is done in several steps. If a crash or internal error |
| // occurred when reporting an error, the nested signal/exception handler |
| // can skip steps that are already (or partially) done. Error reporting will |
| // continue from the next step. This allows us to retrieve and print |
| // information that may be unsafe to get after a fatal error. If it happens, |
| // you may find nested report_and_die() frames when you look at the stack |
| // in a debugger. |
| // |
| // In general, a hang in error handler is much worse than a crash or internal |
| // error, as it's harder to recover from a hang. Deadlock can happen if we |
| // try to grab a lock that is already owned by current thread, or if the |
| // owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the |
| // error handler and all the functions it called should avoid grabbing any |
| // lock. An important thing to notice is that memory allocation needs a lock. |
| // |
| // We should avoid using large stack allocated buffers. Many errors happen |
| // when stack space is already low. Making things even worse is that there |
| // could be nested report_and_die() calls on stack (see above). Only one |
