I missed mentioning that I am building for ARCH=x86 compiling as 64-bit EFI
payload with gcc (Debian 8.3.0-6) 8.3.0 Configured with:
../src/configure -v --with-pkgversion='Debian 8.3.0-6'
 --with-bugurl=file:///usr/share/doc/gcc-8/README.Bugs
 --enable-languages=c,ada,c++,go,brig,d,fortran,objc,obj-c++ --prefix=/usr
 --with-gcc-major-version-only --program-suffix=-8
 --program-prefix=x86_64-linux-gnu- --enable-shared --enable-linker-build-id
 --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix
 --libdir=/usr/lib --enable-nls --enable-bootstrap --enable-clocale=gnu
 --enable-libstdcxx-debug --enable-libstdcxx-time=yes
 --with-default-libstdcxx-abi=new --enable-gnu-unique-object
 --disable-vtable-verify --enable-libmpx --enable-plugin --enable-default-pie
 --with-system-zlib --with-target-system-zlib --enable-objc-gc=auto
 --enable-multiarch --disable-werror --with-arch-32=i686 --with-abi=m64
 --with-multilib-list=m32,m64,mx32 --enable-multilib --with-tune=generic
 --enable-offload-targets=nvptx-none --without-cuda-driver
 --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu
 --target=x86_64-linux-gnu

While at it, I attached the defconfig. The magicvar crash is reproducible
after applying this patch:
