>Description:
I am testing some builds with tinderbox and as a dependancy I need to build
opencv-core. The sample logs compare a tinderbox build using releng/9.0 amd64
against one using stable/9 amd64 - both with CC=clang CXX=clang++ CPP=clang-cpp
ARCH=amd64 set in scripts/etc/env/build.{BUILDNAME}. I get the same issue with
stable/9 ARCH=i386 builds as well as 10-CURRENT.
My base system is 9.0-RELEASE with a clang built world/kernel on a corei5 with
8GB
There is another open pr mentioning an opencv clang failure -- pr-160856 -- It
is a different error (from 9.0 beta2) that would appear to have been fixed
before 9.0 release.
My tinderbox 9.0 jails were compiled 12/march - svn checkout .../releng/9.0 -
the 9-STABLE jails 21/march - svn checkout .../stable/9
A build using 9.0-amd64-clang will compile opencv-core
A build using 9-STABLE-amd646-clang does not, with the opencv-core compile
ending in an assertion failure followed by a stack dump.
