The `shaNI` variable is not a boolean, but has three possible values:
0 (undetermined), 1 (SHA instructions
The bug report says the 8171M and 8272CL have the problem. After applying the

The trap and jobs builtins can be used to report information about
traps and jobs. This works when they're called from the current
shell but in a child shell the required information is usually
cleared. Special hacks allow:
- trap to work with command substitution;
- jobs to work with command
