--- Comment #1 from Tom Tromey <tromey at sourceware dot org> ---
FWIW I couldn't reproduce on Fedora 36, which has GCC 12.
However based on the stack trace I suspect it has to do with
the precise DWARF being emitted:

    #5 std::vector<dwarf_stack_value, std::allocator<dwarf_stack_value>
>::~vector() /usr/include/c++/13/bits/stl_vector.h:735 (gdb+0x751dfa)
    #6 dwarf_expr_context::~dwarf_expr_context()
/data/vries/gdb/src/gdb/dwarf2/expr.h:124 (gdb+0x751dfa)
