[vbox-dev] VirtualBox 5.1 xpcom custom frontend problems

I wanted to upgrade our custom framebuffer client from VirtualBox 5.0.20 to
the latest 5.1.22 and encountered some issues. Since I haven't been
following what is new in 5.1 I just wanted to know if I can get some quick
1) GCC version. Previously when I used 5.0.20 I compiled my frontend
explicitly with gcc-4.9 since using gcc 5 which had binary
incompatibilities lead to crashes. I assume now I should be compiling my
code with gcc-5 ? I tried that but had a crash in xpcom strlen when calling
LockMachine, are there any additional things beside the compiler version
that I should be aware of? I'll check if that happens with the xpcom sample
provided in the sdk as well.
2) Previously I was using setuid on the executable otherwise I could not
instantiate the xpcom object. Now when I do that I can not list the
machines. So have there been any changes to the permission requirements? Is
it safe to run my xpcom based framebuffer frontend without setuid?
Thanks in advance.
