| 288 // possible that the error handler itself may crash or die on an internal | |
| 289 // error, for example, when the stack/heap is badly damaged. We must be | |
| 290 // able to handle recursive errors that happen inside error handler. | |
| 291 // | |
| 292 // Error reporting is done in several steps. If a crash or internal error | |
| 293 // occurred when reporting an error, the nested signal/exception handler | |
| 294 // can skip steps that are already (or partially) done. Error reporting will | |
| 295 // continue from the next step. This allows us to retrieve and print | |
| 296 // information that may be unsafe to get after a fatal error. If it happens, | |
| 297 // you may find nested report_and_die() frames when you look at the stack | |
| 298 // in a debugger. | |
| 299 // | |
| 300 // In general, a hang in error handler is much worse than a crash or internal | |

| 302 // try to grab a lock that is already owned by current thread, or if the | |
| 303 // owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the | |

| 305 // lock. An important thing to notice is that memory allocation needs a lock. | |
| 306 // | |
| 307 // We should avoid using large stack allocated buffers. Many errors happen | |
| 308 // when stack space is already low. Making things even worse is that there | |
| 309 // could be nested report_and_die() calls on stack (see above). Only one | |
