            Bug ID: 30534
           Summary: program received "Illegal instruction" when using
                    systemtap set a probe and hit the probe
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: runtime

  Target Milestone: ---

I am using systemtap to set a user-space probe for any Linux program et. "ls".
If the probe is hit, the program will get a signal "signal 4 (Illegal
instruction)".

------------------------------------------------
# stap dbg-core.stp -c /usr/bin/ls
WARNING: Child process exited with signal 4 (Illegal instruction)
start debug coredump

WARNING: /usr/bin/staprun exited with status: 1
Pass 5: run failed.  [man error::pass5]
-------------------------------------------------

----------- piece code of dbg-core.stp ---------
probe process("/lib64/libc.so.6").function("_IO_new_fclose").return
{
    printf ("call _IO_new_fclose()")
}
------------------------------------------------  

My Linux system info is as below:
