We resolve actually quite a few functions to a null pc:
$ stap -l 'process("/usr/bin/stap").function("*")' -vv 2>&1 | grep pc=0x0 | wc -l
1917
These null pcs get carried all the way into the stap_uprobe_specs array. It
doesn't seem to have any ill effect at runtime, but it's doubtful that probes at
offset 0 in a module are of any use.
Depending on the root cause, we should either skip over these null addresses, or
search further for what the real entrypc should be.
