But it uses multiple processes and maybe you don't see the output from others?
Google suggests something like:
export ASAN_OPTIONS="log_path=/tmp/asan.log" dhcpcd
but I am not sure our version of the sanitziers already support that.
You may find others ways to reliably capture stderr/stdout of the various
processes by changing code though, or simply ktrace -i the whole thing.
But this is just a guess, and maybe something totally different is going on.
