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

325 // We should avoid using large stack allocated buffers. Many errors happen | |
326 // when stack space is already low. Making things even worse is that there | |
