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

--program-prefix=x86_64-linux-gnu- --enable-shared --enable-linker-build-id

--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:
