Package: squid Version: 5.1-2 Severity: important Hello.
Update from 4.13-10 to 5.1-2 leads to periodic crashes in auth code. The puzzling thing is that in all collected core files (13 pieces) crash occures on the same auth token (username/password), while office has about 50 active users, and all but one pass authorization without crashes. In other office, where authorization is not used, the same squid version (5.1-2) runs perfectly. # gdb -c core.18793 -f /usr/sbin/squid -ex 'info reg' -ex 'x/16i $pc' -ex 'thread apply all bt full' -ex quit GNU gdb (Debian 10.1-2) 10.1.90.20210103-git Copyright (C) 2021 Free Software Foundation, Inc.
