Thanks. I try gdb.
find the problem is
.........
#6 0x0805d289 in perf_event::set_event_name (this=0xc94ff4,
event_name=0x8089a6b "power:power_frequency")
at perf/perf.cpp:152
..............
I find void perf_event::set_event_name(const char *event_name)
150 {
151 if (name)
152 free(name);
153
154 name = strdup(event_name);
155 char *c;
I think if(name) is the problem, so I change it with if(!name).
It can work now.
Is it a bug??
