Bug ID: 23572
Summary: Test file systemtap.base/target_set_thread.exp hangs
forever on kernel 4.16.16 (Fedora 27)
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: testsuite
Assignee: systemtap at sourceware dot org
Reporter: agentzh at gmail dot com
Target Milestone: ---
Created attachment 11212
--> https://sourceware.org/bugzilla/attachment.cgi?id=11212&action=edit
stap-report output on the same box for the same installation
I tried running the full official test suite of the current master (HEAD is
commit 1d530d0409) and the test suite never completes due to the test file
`systemtap.base/target_set_thread.exp` hanging forever.
The `ps` command shows the following processes always hanging (already hanging
there for more than 30min as of this writing):

Oh, BTW, I used the following command to run the test suite:
```
sudo make -j5 installcheck-parallel
```

Running the offending test file `systemtap.base/target_set_thread.exp`
individually does not seem to reproduce the hang. Weird.
