[Qemu-devel] aarch64-linux-user compilation error

[Pranith Kumar]

Hi,

I am getting a strange compilation error lately for aarch64-linux-user. I
think it is somehow related to TYPE_PTRVOID handling but my investigation has
not led to anything concrete. I think this is a compiler error since the build
passes on an other system with gcc-6.

Info: ubuntu 16.04 x86_64 system

$ gcc --version
gcc (Ubuntu 5.4.1-2ubuntu1~16.04) 5.4.1 20160904
