Package: qtcreator
Version: 3.3.0+dfsg-1
Severity: normal
Hi,
qtcreator hangs on exit and generates CPU load. It keeps hanged until killed. It looks that the issue is somehow related to OpenGL libraries.
The problem doesn't occur when qtcreator is launched from gdb, but it can be reproduced when gdb is attached to running process.
There are zombie processes right after starting qtcreator, don't know if it's related:
$ ps -ef |grep qtcreator

When strace is attached, I can see following output repeated until qtcreator is killed:
