301 // This is the main function to report a fatal error. Only one thread can | |

303 // possible that the error handler itself may crash or die on an internal | |
304 // error, for example, when the stack/heap is badly damaged. We must be | |
305 // able to handle recursive errors that happen inside error handler. | |
306 // | |
307 // Error reporting is done in several steps. If a crash or internal error | |
308 // occurred when reporting an error, the nested signal/exception handler | |
309 // can skip steps that are already (or partially) done. Error reporting will | |
310 // continue from the next step. This allows us to retrieve and print | |
311 // information that may be unsafe to get after a fatal error. If it happens, | |
312 // you may find nested report_and_die() frames when you look at the stack | |
313 // in a debugger. | |

318 // owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the | |
319 // error handler and all the functions it called should avoid grabbing any | |
320 // lock. An important thing to notice is that memory allocation needs a lock. | |
321 // | |
322 // We should avoid using large stack allocated buffers. Many errors happen | |
323 // when stack space is already low. Making things even worse is that there | |
324 // could be nested report_and_die() calls on stack (see above). Only one | |
