BT from gdb for the WebProcess (forced)

Epiphany 3.22.5 and WebKit 2.15.4

I'm running Epiphany with the dconf key:

"process-model" = "shared-secondary-process"

And the env variable:

"export LIBGL_DRI3_DISABLE=1"

The compilation was done with CMake args:

'-DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DEBUG=fatal-criticals -DG_DISABLE_CAST_CHECKS"'

After visiting several pages, eventually, my last opened tabs won't finish loading and rendering the page.

The tab shows the loading progress but never gets to finish. Trying to reload or stop and reload won't help. Also, the rest of the tabs are in an unresponsive state. There is no SIGSEV nor the desktop gets a high load but, although ehy is not frozen, the tabs content seems to be.

This bug is not reproducible in a predictable way.
