            Bug ID: 229830
           Summary: [truss] throws an assertion failure after the trussed
                    process got killed
           Product: Base System
           Version: 11.1-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: bsdpr at phoe.frmug.org

I used truss to try to identify what syscall caused the kernel to SIGKILL a jvm
and log "out of swap space" to the console while plenty of space was still
available in the swap. (This behavior nor this bug report are java-related, I
previously observed it with different commands, I desired to understand that
behavior and had a ready test case at hand.) I was unable to observe the
curlpit syscall because truss triggered an assertion failure before printing
anything related. The assertion is:

Assertion failed: (LIST_NEXT(info->curthread, entries) == NULL), function
find_exit_thread, file /usr/src/usr.bin/truss/setup.c, line 337.

The system was compiled from svn revision 329283.
