    Description

      There are some gaps in codebase that a MSAN debug builder may sufficiently exercise.

      -DWITH_SAFEMALLOC=OFF required to maintain stack sanity in large stack cases. (becomes default with MDEV-37052 proposed changes).

      To gain some addition coverage, lets do this on aarch64 as an alternate architecture. Main reason it has a rr implementation that can be used to trace this.

      Gaps found so far.

      • MDEV-36542 Remove compile options for faking initialisation #3961
        PR include MDEV-34388 stackframe size which under clang/debug exceeds the 16k limit in a few more places. MYSQL_MAINTAINER_MODE=NO is a hack to get past -Werror conditions.

      https://github.com/MariaDB/server/commit/e843033d0233927b8f51d7dbe21993bdfb01ecdf

      • new implementation - valist (ap) variable is not a pointer - compile faults on aarch - also work around not needed any more.
