BT from gdb for the WebProcess

Epiphany 3.24.1 and WebKit 2.17.4.

The compilation was done with CMake args:

'-DDEBUG_FISSION=OFF -DPORT=GTK -DCMAKE_BUILD_TYPE=Release -DENABLE_MINIBROWSER=ON -DCMAKE_C_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS" -DCMAKE_CXX_FLAGS_RELEASE="-O0 -g -DNDEBUG -DG_DISABLE_CAST_CHECKS"'

After visiting several pages, eventually, the WebProcess hits a SIGSEV. Epiphany is completely closed.

This bug is not reproducible in a predictable way.

During epiphany's crashing/closing, this SIGSEV also happened.

What makes this crash? g_source_set_ready_time's source is dangling?

These 2 BTs are the ones showing the crash. The actual reason why they happened in the first place, I don't know :(

Another similar BT that I got recently.

I cannot explain how it happened neither reproduce.
