Here the message is:
/usr/include/c++/8/debug/vector:417:
Error: attempt to subscript container with out-of-bounds index 1899910496,
but container only holds 98 elements.
Objects involved in the operation:
sequence "this" @ 0x0x555f98a58bc8 {
type = std::__debug::vector<lyx::Graph::Vertex,
std::allocator<lyx::Graph::Vertex>
>; }
Abort (core dumped)
If using attached, I got no crash, but the list of indexes used while removing
the format
is scarifying.
