The following patch calls truncate (0) instead of m_vecpfx.m_num clearing, and truncate takes care of that destruction: unsigned l = length (); gcc_checking_assert (l >= size); if (!std::is_trivially_destructible <T>::value) vec_destruct (address () + size, l - size); m_vecpfx.m_num = size; 2025-01-16 Jakub Jelinek <ja...@redhat.com> PR ipa/118400 * vec.h (vec<T, va_heap, vl_ptr>::release): Call m_vec->truncate (0) instead of clearing m_vec->m_vecpfx.m_num.
