--- Comment #1 from seb128 at debian.org ---
Alright, after adding some swap to the instance, backtrace from doing

$ GDK_SYNCHRONIZE=1 /usr/lib/aarch64-linux-gnu/webkit2gtk-4.0/MiniBrowser

and using

$ gdb /usr/lib/aarch64-linux-gnu/webkit2gtk-4.0/WebKitWebProcess cdump

(is setting the env for the browser enough to have it for the rendering process as well or would something else be needed?)
