No, this instruction or PC is not in myClient nor in myServer. But i can 
find the instruction in a shared lib which myServer uses.

btw. i use l4re-snapshot-2014022818.

Well then, where do i find the cause for the page error?
Do i need a deeper unterstanding of the stack, or shall i just look at 
the instructions around PC=15c7a8 ?
