Running it as root in the home directory 
(/data/data/berserker.android.apps.sshdroid/home) fixed those 
errors. I don't know how to add non-root users though.

Thanks, I got gdb-server running. In core.thread and some later 
modules it stops because of SIGUSR1 and SIGUSR2; I guess I should 
make gdb ignore those? After continuing from all the SIGUSR 
signals, I get the segfault that occurs after 
std.internal.math.gammafunction passes:

Program received signal SIGSEGV, Segmentation fault.

I'm guessing this is the same issue you mentioned.
