How reproducible:
happens all the time, see below

Steps to Reproduce:
1. run 'su'
2. make sure you switch to ksh by typing 'ksh', then suspend the root (ksh) shell using  'suspend'
3. gives 'Segmentation fault', also running 'jobs' shows nothing after that
4. run 'dmesg | tail' to see "[245682.112734] ksh[20922]: segfault at 30 ip 0806f670 sp bfb16d50 error 4 in ksh[8048000+14d000]"
