There is not much that can be learned from truss output in a case like this. No program should ever execute an illegal instruction. When one does, it means the program in question has a bug. If this program usually works ok and this illegal instruction is a rare exception, my guess would be that the program was fed some really screwy data. The program is attempting to process data that it should reject. So I would check the program's input looking for anything really strange.

NAME
isalist - display the native instruction sets executable on this platform
SYNOPSIS
isalist
DESCRIPTION
isalist prints the names of the native instruction sets executable on this platform on the standard output, as returned by the SI_ISALIST
command of sysinfo(2).
The names are space-separated and are ordered in the sense of best performance. That is, earlier-named instruction sets may contain more
instructions than later-named instruction sets; a program that is compiled for an earlier-named instruction sets will most likely run
faster on this machine than the same program compiled for a later-named instruction set.
Programs compiled for instruction sets that do not appear in the list will most likely experience performance degradation or not run at all
on this machine.
The instruction set names known to the system are listed in isalist(5). These names may or may not match predefined names or compiler
options in the C language compilation system,
