Hi I just updated edk2 package and trying to build a BaseTools module.

But it reported an error like the following

brotli/c/dec/decode.c:2033:41: error：argument 2 of type ‘const uint8_t *’ {或称 ‘const unsigned char *’} declared as a pointer [-Werror=vla-parameter]
 2033 |     size_t encoded_size, const uint8_t* encoded_buffer, size_t* decoded_size,
      |                          ~~~~~~~~~~~~~~~^~~~~~~~~~~~~~

I'm using gcc 11 and with manjaro system. I would like to ask if it is a bug and how to fix it. Thanks a lot!!

Apply this pull request and no more errors: https://github.com/tianocore/edk2/pull/2346

Or wait for it to be merged.

Tried with gcc (Debian 11.2.0-12) 11.2.0
