That is my current best guest as well, but I could not confirm it because /usr/local/sbin/pkg-static is stripped by default and I could not see any function names when I attached gdb(1) to it. Will rebuild pkg(8) shortly WITH_DEBUG to get more information. Other alternative to PKG_NOCOMPRESS=1 could be PKGSUFFIX=.tbz (pkg-static create -f tbz ...), will play with that as well. Thanks, ./danfe
