Subject: [PATCH] build : silence misleading -Warray-bounds warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There is a -Warray-bounds warning from g++ 13.2.1 in
test-llama-grammar.cpp that is a false-positive because there is a
ternary that special-cases zero in the std::vector code.

/usr/include/c++/13.2.1/bits/stl_algobase.h:398:17: warning: array subscript 0 is outside array bounds of ‘const llama_grammar_element* [0]’ [-Warray-bounds=]
  398 |         { *__to = *__from; }
      |           ~~~~~~^~~~~~~~~
