>Description:
Deleting children then the parent variable object causes gdb to detach from the process, here is an example of the internal commands:

(gdb) -var-list-children "KDEV138"
^done,numchild="8",children=[child={name="KDEV138.0",exp="0",numchild="0",type="int"},child={name="KDEV138.1",exp="1",numchild="0",type="int"},child={name="KDEV138.2",exp="2",numchild="0",type="int"},child={name="KDEV138.3",exp="3",numchild="0",type="int"},child={name="KDEV138.4",exp="4",numchild="0",type="int"},child={name="KDEV138.5",exp="5",numchild="0",type="int"},child={name="KDEV138.6",exp="6",numchild="0",type="int"},child={name="KDEV138.7",exp="7",numchild="0",type="int"}]
...
(gdb) -var-delete "KDEV138.0"
^done,ndeleted="1"
...
(gdb) -var-delete "KDEV138"
(gdb) Process exited

The process is still running but no longer debugged at this stage.  This appears to be a consistent problem when viewing the contents of an int [] member of a template class, but I don't know how significant this is.

The commands are issued by kdevelop, but prior deletion of the children would appear unnecessary: removing them avoids the problem.
