Aproximately the same time we switched on CURRENT to the CURRENT LLVM13 version and also, after the compilation of a fresh OS with LLVM13, the upgrade from bind-9.16.22 to bind-9.16.23 took place as well as ASLR being the default. Since then named is crashing with a mysterious segmentation fault (see PR 259921, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259921). Disabling ASLR as recommended to check whether ASLR triggers the SegFault did not solve the problem, so I suspect a miscompilation due to llvm13. On 13-STABLE bind-9.16.23 seem not to have this behaviour. I'm floating like a dead man in the water, can someone help? Kind regards, oh
