/usr/bin/../lib/gcc/x86_64-linux-gnu/12/../../../../include/c++/12/bits/stl_tempbuf.h:263:8: error: 'get_temporary_buffer<QVector<AzQtComponents::StyledDetailsTableModel::InternalTableData> *>' is deprecated [-Werror,-Wdeprecated-declarations]
  263 |                 std::get_temporary_buffer<value_type>(_M_original_len));

This function is part of the C++ Standard Library and has been marked as deprecated in modern C++ standards (C++17 and later). The purpose of get_temporary_buffer was to allocate uninitialized memory, but it has been deprecated due to the availability of better alternatives for managing dynamic memory.

You can allocate memory dynamically and want automatic cleanup, you can use std::unique_ptr:

std::unique_ptr<QVector<AzQtComponents::StyledDetailsTableModel::InternalTableData>[]> buffer = std::make_unique<QVector<AzQtComponents::StyledDetailsTableModel::InternalTableData>[]>(n);
