error meaasge when quit application

[casanova]

Hi i'm using ti am335x evm platform. When I quit the demo program and my program it will show the error message with
"*** glibc detected *** /usr/bin/Setting_launcher: double free or corruption (!prev): 0x00028d90 ***"
and the process with stay in the process table. You have to kill it or you can't create the same process.
My console command was bellow
"/usr/bin/Setting_launcher -qws -display powervr"

Ti EVm is using Qt-embedded 4.8.4 and I have try use qt-embedded 4.8.5 ,i has the same program. But when I don't use the command line with "-display powervr" ,i won't display any message and close normally.

Any one know how to avoid the issue ?

Thanks !!!!!
