If I convert
128.0.0.0 to decimal the result is 2,147,483,648 which exceeds the maximum 32-bit signed integer value for variables 2,147,483,647 declared as integers. So it's clear now why the script that uses the native
lshift, rshift, or bitwise operations is causing an awk segmentation fault with IP's greater than
128.0.0.0 and the script that uses the custom
bit_lshift, bit_rshift, bit_or bitwise operations doesn't.
End of a long story =(
The only time segmentation fault isn't programmer error is when your RAM is faulty or someone pulled a disk they really shouldn't have. This isn't expected behavior, this is still a bug.

NAME
sys_attrs_kevm - KEVM (Kernel Event Manager) subsystem attributes
DESCRIPTION
This manpage lists and describes attributes for the Kernel Event Manager subsystem. See evm(5) for more information about Event Manager
software.
An asterisk preceding the name of an attribute in the following list means that the attribute can be configured at run time. Values of
other attributes cannot be changed without rebooting the system.
A value that can be used to reinitialize all of the
attributes. Changing to any non-zero value causes all the attributes to be reset to zero, and then itself is automatically reset
to zero.
Default value: 0
Minimum value: 0
Maximum value: 2,147,483,647
If you use to change the value of the updated attribute values are not visible until you exit and restart
The number of EVM events currently queued in kernel space for
collection by the EVM daemon. This attribute is query only.
The size (in bytes) of the fixed buffer used to queue any EVM events
that are posted while the kernel is executing at interrupt level. Events are moved out of the buffer as soon as the system
returns to normal operating mode. The default buffer size should be adequate for most systems.
Default value: 65, 536 (bytes)
Minimum value: 1
Maximum value: 1,844,674,407,370
A value that indicates whether a process (such as
currently has or does not have the interface in an open state. The value 1 means that a process has the interface open (always
the case if is running) and the value 0 means that no process has the interface open. This attribute is query only.
The major device number being used by the
interface. This attribute is query only.
The number of EVM events that have been posted in the kernel since the
the system was started or the counter was reset. You can reset directly, or by changing to a non-zero value.
Minimum value: 0
Maximum value: 2,147,483,647
The number of EVM events that have been read from kernel space by the
EVM daemon since the system was started or the counter was reset. You can reset manually or by changing to a non-zero value.
Minimum value: 0
Maximum value: 2,147,483,647
The highest number of EVM events that have been queued in kernel space
waiting to be collected by the EVM daemon since the system was started or the counter was reset. You can reset manually or by
changing to a non-zero value.
Minimum value: 0
Maximum value: 2,147,483,647
