Hello.

In the latest version of Genode didn't work Arora browser.
I have messages in log:
no RM attachment (READ pf_addr=0 pf_ip=14b05e4 from 60e000)
virtual void Genode::Pager_activation_base::entry(): Could not resolve pf=0
ip=14b05e4

I tried to investigate this issue. I launched Arora with gdb-server:
Program received signal SIGSEGV, Segmentation fault.

What may cause this error? How to debug in such cases?
