[Playerstage-users] Player 3.0.2 fails with segmentation fault

[mandeep b. <man...@gm...>]

Hi,
 I could not understand why this happened, i did not find a post
regarding this happening to anyone.
I compiled Player 3.0.2 on openSuse 11.2 64 bit. When I ran player
just for test, it displayed this
_______________________________
$player
Registering driver
Player v.3.0.2
USAGE:  player [options] [<configfile>]

Where [options] can be:
  -h             : print this message.
  -d <level>     : debug message level (0 = none, 1 = default, 9 = all).
  -p <port>      : port where Player will listen. Default: 6665
  -q             : quiet mode: minimizes the console output on startup.
  -l <logfile>   : log player output to the specified file
  <configfile>   : load the the indicated config file

The following 117 drivers were compiled into Player:

    Segmentation fault
____________________________________


While listing the drivers player gave segmentation fault..

I just did a quick core dump
i got

(gdb) bt
#0  0x00007f5d2f996db8 in DriverTable::SortDrivers() ()
   from /home/mandeep/Robotics/player-3.0.2/build/libplayercore/libplayercore.so.3.0
#1  0x0000000000402486 in PrintUsage() ()

Also on debugging a little the problem occurs when in
DriverTable::SortDrivers() list for sorting is formed
@
for(DriverEntry* entry = head; entry; entry = entry->next)
          sortedlist[i++] = entry->name;
i.e head pointer might be wrong


Thanks,
Mandeep
