I'm not seeing this problem on 2.6.18-348.el5 (s390x) or on
2.6.32-358.el6.s390x, so I'm closing it.

The unused variable will be optimized, try it with -u. The problem won't exist
on x86, seems specific to s390.

Different scenarios under which system hangs
1) printing pp() inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
funcname = pp();
printf("========%s \n",funcname);
}
==============================
2)printing probefunc() inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
funcname = probefunc();
printf("========%s \n",funcname);
}
==============================
Different scenarios under which system works well.
1) printing "hello" message and calling probefunc() or pp()(without printing
their value) inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
funcname = probefunc();
printf("hello");
}
==============================
