298 |

// Error reporting is done in several steps. If a crash or internal error |

303 |
// occurred when reporting an error, the nested signal/exception handler |
|
304 |
// can skip steps that are already (or partially) done. Error reporting will |
|
305 |
// continue from the next step. This allows us to retrieve and print |

306 |
// information that may be unsafe to get after a fatal error. If it happens, |

// error handler and all the functions it called should avoid grabbing any |
|
315 |
// lock. An important thing to notice is that memory allocation needs a lock. |
|
316 |
// |
|
317 |
// We should avoid using large stack allocated buffers. Many errors happen |
