This could be heap corruption, I think.

Can you please build Emacs with ASAN?  Something like:

  git clean -xdf
  ./autogen.sh
  ./configure CFLAGS="-g -O0 -fsanitize=address -fno-omit-frame-pointer" \
              LDFLAGS="-fsanitize=address -fno-omit-frame-pointer"
  make

Everything above in the root of your Git worktree.

Then start Emacs like this:

  cd src
  lldb emacs
  run

and do what you did to make it crash.  If it's a heap corruption, and
ASAN can detect it, it will break into LLDB at that point.  Then please
print backtraces and so on, as Eli said.
