+Subject: [PATCH] Align the stack on entry to __tls_get_addr()
+
+Old versions of gcc (4 & 5) didn't align the stack according to the
+AMD64 psABI when calling __tls_get_addr(). Apparently new versions of
+gcc (7) got much more aggressive about vectorizing and generating MOVAPS
+instructions, which means old binaries built with the buggy versions of
+gcc are much more likely to crash when using versions of glibc built
+using gcc 7.
+
+For example, a large number of Linux games built using the Unity game
+engine and available for purchase on Steam.
