# GCC 14 on ppc64le emits a false-positive -Wfree-nonheap-object inside
# std::vector<uint8_t>::push_back / _M_realloc_append when inlining
# random_input() at -O3 (GCC PR 115016). The warning fires in
# new_allocator.h on a pointer the compiler loses track of after
# reserve() + push_back(). Recheck: remove this block and build
# execution_fuzz_core.cpp on ppc64le at -O3 with the next GCC upgrade.
