media-libs/coin-3.1.3-r2::gentoo was built with the following: USE="bzip2 threads zlib -debug -doc -javascript -openal -simage -static-libs" ABI_X86="(64)"
Somewhere in the code there is manipulation of the memory location of a class object before its constructor is called. Adding the following to src_configure should fix the problem: if tc-is-gcc && [[ $(gcc-major-version) -ge 6 ]] ; then append-cppflags -flifetime-dse=1 fi
Created attachment 482402 [details, diff] coin-3.1.3-gcc-6.patch I found a patch for this issue in a fedora bug. The issue was an improper initialization in a constructor. Previous versions of GCC did the right thing, but gcc 6 enables additional optimization (mentioned above by Peter Levine) that leaves memhandler uninitialized. Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1323159 Fedora Patch: http://pkgs.fedoraproject.org/cgit/rpms/Coin3.git/commit/?id=ca89ec7227943bdec800ee51b920f578fab87b05
Created attachment 482404 [details] coin-3.1.3-r3.ebuild Ebuild that applies the above patch.
