Are you compiling with optimization turned off?  If
optimization is enabled, the compiler may have optimized away
the whole call.   Are you saying you can put a breakpoint at
line 9 and it stops there, but it never gets there by doing
"step" commands?  That's very strange.

Nope.  We've got three of them and we never had to do anything
other than set the IP addresses.
