Description
Version of Kakoune
v2024.05.18
Reproducer
The editor crashed after executing the following command about 10 times, specifically when it encountered a newline:
exec "<esc><c-s>;<a-?> +[^ ]+<ret><a-;><H><a-d>2<c-o><i>"
The command was executed without kak-lsp on, in a kakrc file.
Outcome
/usr/include/c++/13.2.1/bits/stl_vector.h:1125: constexpr std::vector<_Tp, _Alloc>::reference std::vector<_Tp, _Alloc>::operator[](size_type) [with _Tp = Kakoune::SelectionList; _Alloc = Kakoune::Allocator<Kakoune::SelectionList, Kakoune::MemoryDomain::Selections>; reference = Kakoune::SelectionList&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Expectations
No response
Additional information
This occurred on Alpine Linux edge, on a release version of Kakoune. I'm using foot --server as my terminal currently. I can attempt to obtain more debug information soon, including reproducing it (which I have only been able to do once so far).
