Package: powertop
Version: 1.97-2
Followup-For: Bug #671836
Dear Maintainer,
don't know is this is same issue or not, but i have similar crash at startup,
last strace output:
open("/proc/cpuinfo", O_RDONLY|O_LARGEFILE) = 3
read(3, "processor\t: 0\nvendor_id\t: Genuin"..., 8191) = 554
open("/sys/devices/system/cpu/cpu0/topology/core_id", O_RDONLY|O_LARGEFILE) = 4
read(4, "0\n", 8191) = 2
close(4) = 0
open("/sys/devices/system/cpu/cpu0/topology/physical_package_id",
O_RDONLY|O_LARGEFILE) = 4
read(4, "-1\n", 8191) = 3
close(4) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
Segmentation fault
there in /cpu/cpu.cpp:
static void handle_one_cpu(unsigned int number, char *vendor, int family, int
model)
{
char filename[1024];
ifstream file;
unsigned int package_number = 0;
unsigned int core_number = 0;
blabla
sprintf(filename,
"/sys/devices/system/cpu/cpu%i/topology/physical_package_id", number);
file.open(filename, ios::in);
if (file) {
file >> package_number;
file.close();
}
package_number is unsigned, but:
cat /sys/devices/system/cpu/cpu0/topology/physical_package_id
-1
may be this is a problem?
