Public bug reported:
On two different riscv64 systems (SiFive HiFive Unmatched, HiFive P550
Premier) running Ubuntu Noble I experienced crashes in
socket_source_dispatch() when it invokes a callback function:
Core was generated by `/usr/bin/epiphany'.
Program terminated with signal SIGSEGV, Segmentation fault.

To reproduce:
* Install Ubuntu 24.40, ubuntu-desktop, gdm3, epiphany-browser on SiFive HiFive
Unmatched board with GPU (such a board is available in the Taipeh lab)
* Run epiphany-browser and load a complex page (e.g. https://www.faz.net).
