Date: Fri, 25 Oct 2019 17:13:00 -0000 [thread overview]
Message-ID: <bug-25133-6586@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=25133
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) } }'.
