  .../prog_tests/trampoline_count.c: In function ‘test_trampoline_count’:
  .../prog_tests/trampoline_count.c:49:9: warning: missing braces around initializer [-Wmissing-braces]
  struct inst inst[MAX_TRAMP_PROGS] = { 0 };
         ^
  .../prog_tests/trampoline_count.c:49:9: warning: (near initialization for ‘inst[0]’) [-Wmissing-braces]
