Hi Norman,
using a separate init to chdir also made the segfault disappear and I
can now successfully run the timer test on Linux [1].

Hi Johannes,
for bootstrapping core, I'd create a custom (statically compiled)
program that merely performs a 'chdir /genode' followed by 'execve
'/genode/core'. This keeps core clean of the bootstrapping magic. This
bootstrapping program can be called '/init' whereas everything
Genode-related resides as '/genode/'.
I have no good idea about the segfault though. It definitely happens in
init, not core because the fault occurs in 'ld.lib.so', which is not
used by core. You may inspect the debug version of the ld.lib.so binary
(using 'objdump -lSd debug/ld-linux.lib.so') at the faulting ip. The
offset from the start of 'ld-linux.lib.so' can be calculated by
subtracting the load address of ld.lib.so (as reported by the kernel)
from the ip of the fault.
Cheers
Norman
