            Bug ID: 24947
           Summary: valid hex and octal sequences not checked for
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bpf
          Assignee: systemtap at sourceware dot org
          Reporter: sapatel at redhat dot com
  Target Milestone: ---

With stapbpf there is no check to see if hex and octal sequences are in a valid
range. For example, if we ran the following script in the LKM backend:

stap -e 'probe oneshot { printf("\x100") }', we would get the following output:

"error: hex escape sequence out of range". 

However, in stapbpf, this error is not outputted.
