The compound literals assigned to "components" only exist within the scope of the if/else block (thanks Mark Thompson for the better explanation). Thus, after this if/else block, "components" ends up pointing to an arbitrary/undefined array. With some compilers and depending on optimization settings, these arbitrary values may end up being the same value (i.e. 0 with GNU GCC 9.x). Unfortunately, the GNU GCC compiler, at least, never prints any warnings about this. This patch fixes this issue by assigning the constant arrays to local variables at function scope and then pointing "components" to those as necessary. Fixes #7915 Signed-off-by: U. Artie Eoff <ullysses.a.eoff@intel.com>
