[Bug translator/4899] New: Can't insert stap probes on empty lines in a C function

["bharata at linux dot vnet dot ibm dot com" <sourceware-bugzilla at sourceware dot org>]

Using SystemTap translator/driver (version 0.5.15/Red Hat elfutils 0.125 built
2007-08-01)

If a probepoint falls on an empty line in a C function, stap throw's a semantic
error. For eg with this stap script,

# kernel/fork.c:1385 happens to be a line w/o any C statements in do_fork() in
the kernel I am using.
probe kernel.function("*@kernel/fork.c:1385") {
        printf("do_fork: %d\n", $clone_flags);
}

The error shown is:
semantic error: no match for probe point while resolving probe point
kernel.function("*@kernel/fork.c:1385")

I would think that stap needs to find the next valid line which has a C
statement and should insert the probepoint there.
