Comment (by Steven Keuchel):

 Duplicate of https://trac.ffmpeg.org/ticket/11251. There are additional
 commits producing the same error in different parts of the code:

 https://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=324899b7483529c336f399022c63721df14663ef
 https://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=98db1409102c5443491c2738aa601531f7f9b938
 https://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=f6d0a41c8ca67672f8e4b3c6e16cb3abd9f379bf

 A (temporary) fix is to add `__volatile__` to the `__asm__` blocks to
 avoid compiling the runtime check of `ff_rv_zbb_support` away.
