Thanks. I followed all the steps but the last one (sysctl -w
kernel.suid_dumpable=2) does not work for me:-( It always gives
    error: "kernel.suid_dumpable" is an unknown key
and even if I use -e cat /proc/sys/fs/suid_dumpable always prints 0.
This is completely unknown territory to me so I don't know how to solve
this!

I've also tried running in valgrind as per Ludovic's suggestion. The
crash occurs exactly as before with valgrind reporting 0 errors:


$ lout -r beginning run 5:

I killed it at this point.
