Hello!

I've attached some code that must be compiled on Minix using g++ (GCC
4.1.1). It's sort of hard for you to run the code since it requires a
kernel hack that installs my own server into the boot image and allows
"init" children to communicate with ti.

The thing with the below code is that both receive() and send() return
error code -110, which means "IPC trap not allowed". However,
sendrec() works fine for some reason. Anyone ever have this problem?
I can't figure it out... On the server side, my code does receive(ANY,
msg) and then send()'s back to msg.m_source just fine. So I'm pretty
much at a loss and was hoping someone here knew the answer... the
answer is probably somewhere in the Minix code too.

Thanks in advance for all your help.
