Bug ID: 25133
Summary: stapbpf foreach loop crashing
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: ---
Using foreach loops with stapbpf cause segmentation faults sometimes. For
example, consider the following script:
$ stap --bpf -e 'global arr probe oneshot { arr["a"] = 0; arr["b"] = 1; foreach
(v = k in arr) { printf("%s", k) } }'.
