| Description |
|
segfaults may have a missing b field. mongosymb.py should be smart enough to ignore it. See this snippet from convo on Slack. I’m running like this: python buildscripts/resmoke.py symbolize -t mongodb_mongo_v5.0_enterprise_rhel_80_64_bit_dynamic_required_display_jstestfuzz_concurrent_replication_1928c8d20941bdaf094507d0b1616ca58d530330_21_07_20_19_56_18 < backtrace.log backtrace.log is attached. This is the problematic line: {"a":"557019C40800"} |

acm for the VDSO issue, should I file a SERVER ticket for Service Arch or do you know if missing "b" is the expected behavior? |

Seems plausible, and consistent with a segfault missing the base address. |

Probably for base. |

acm Not familiar with the origin or the significance of the letter "b" as the field name, but its value should correspond to ELF's sh_addr. |
