Hi,<br><br>
for future, can you just paste the test output to email, instead of sending screenshots of text?<br><br>
You're not providing much information, such as LTP version, kernel, architecture or distro.<br>
Or if it worked previously and started failing only now. So it's difficult for anyone to<br>
try reproduce your steps.<br><br>
Output is unusual, status codes suggest child running into SIGSEGV and SIGILL at some<br>
point after eatup_mem(). Did you try to run this with gdb, strace or look at core files?<br><br>
