Comment:

 The problem is specific to arm/neon code.

 The build succeeded on our arm64 buildbot machines; something must be
 different about your build. It appears to be that you are using the debug
 variant and we are not: the buildbot builds used `-DNDEBUG` while your
 build did not. Defining `NDEBUG` turns off assertions.

 I also notice in the log is that you are using the macOS 11 SDK but I
 don't think that's relevant.

 The code on line 272 of the file wiener_convolve_neon.c reads:

 {{{#!c
     assert(x_step_q4 == 16 && y_step_q4 == 16);
 }}}

 I do not see anywhere that `x_step_q4` or `y_step_q4` are defined in this
 file. They are defined in other files. Maybe this was copied from another
 file without ever testing with assertions enabled.

 The worksround would be to remove that line, or don't use the debug
 variant.

 AV1/-/issues/2202
