@micwoj92 Those flags are already in my /etc/makepkg.conf. I tried re-compiling the latest version of the package (and explicitly setting those flags) but I still get the segfault.

I did some debugging and found out it's crashing in ATIMach64Detect() on outr() or outb() looks like something is wrong with the memory mapping?

@benpicco this package is already marked out of date

Try building with

  export CFLAGS=${CFLAGS/-fno-plt}
  export CXXFLAGS=${CXXFLAGS/-fno-plt}
  export LDFLAGS=${LDFLAGS/,-z,now}

There is a new upstream version
