Bug #: 14924
Summary: warn on complex $ptr->foo expressions in .return
probes
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
AssignedTo: systemtap@sourceware.org
ReportedBy: fche@redhat.com
Classification: Unclassified
Some users are confused by stap's automatic function-call entry-time
snapshotting of $foo->bar->baz expressions in .return probes. While it's
probably not a good idea to change the behavior (maybe not even with
--compatible), we could emit a warning, referencing @entry() (see also bug
#14437).
