Package: ircd-hybrid Version: 1:8.2.24+dfsg.1-1 Severity: grave Hi,
I just upgraded to buster and ircd keeps crashing. One case with a segfault in strcmp, other times with glibc aborts. Running with valgrind shows: ==4562== Invalid read of size 8 ==4562== at 0x127E10: dlinkDelete (list.c:125) ==4562== by 0x12C7FB: rem_request (res.c:107) ==4562== by 0x12C7FB: res_readreply
