error: size of array element is not a multiple of its alignment

Problem: This problem occurs when compiling the latest master branch of Xonotic on GCC 11.1.0 on Archlinux.

The problem is:

../../../dpsoftrast.c:239:22: error: size of array element is not a multiple of its alignment
  239 | typedef ALIGN(struct DPSOFTRAST_State_Thread_s
      |                      ^~~~~~~~~~~~~~~~~~~~~~~~~

Looks like modifying line 45, #define ALIGN(var) var __attribute__((__aligned__(16))) and change 16 to 8 fixes this issue, but this can be dangerous.

Also, this problem doesn't occur on GCC 10, Clang 12.0.1.

For now, game works fine, alignment set to 8.
