>Description:
When I use torsocks to proxy an https request with curl or w3m,
they (w3m or curl) works correctly but exit with segmentation
fault and produce a core dump
>How-To-Repeat:
pkg_add tor torsocks curl
rcctl enable tor
rcctl start tor
torsocks curl https://openbsd.org
or
torsocks w3m https://openbsd.org | cat -
>Fix:
I don't know but please find backtrace of core dumps of curl and w3m

Core was generated by `curl'.
