Continuing "Unbound crashes periodically with signal 11"

[ryan-b]

I hope it's not a faux pas to resurrect another thread here. I'm unable to update the thread https://forum.netgate.com/topic/160005/unbound-crashes-periodically-with-signal-11/104 because the 2.5 Development Snapshots category is retired.

I have a SG-3100 which was rock solid until upgrading from 2.4.x to 21.02-RELEASE-p1. Now I've run into 3 instances of unbound crashing w/ sigsegv.

I'm able to collect core files from unbound after it segfaults, but they're not much good without symbols. My SG-3100 has a /usr/lib/debug directory containing .debug variants of the base system (ex: libc.so.7.debug), but gdb says that the debug information from those files don't match what's actually on my base system (warning: the debug information found in "/usr/lib/debug//lib/libc.so.7.debug" does not match "/lib/libc.so.7" (CRC mismatch).).

Is it possible to get my hands on the unstripped/debug_info libraries corresponding to the pfSense distribution currently installed on my device? I poked around https://firmware.netgate.com/pkg/pfSense_plus-v21_02_armv7-core/All/ and only located the stripped base system.

Thanks!
