Bug ID: 16406
Summary: pass-5 build-id mismatch when -c cmd has same name as
module
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: jlebon at redhat dot com
For example, the following works:
$ stap -e 'probe process.function("main") { println("main entered") }' -c ls
file1 file2
main entered
$
But this fails:
$ stap -e 'probe process.function("main") { println("main entered") }' -c ls -m
ls
ERROR: Build-id mismatch [man error::buildid]: "/usr/bin/ls" byte 0 (0xdc vs
0x00) address 0xffffffffa06862bc rc -14
WARNING: Child process exited with signal 9 (Killed)
WARNING: /usr/bin/staprun exited with status: 1
Pass 5: run failed. [man error::pass5]
$
I'm guessing the runtime is getting confused during build-id checking between
the module name and the name of the target.
