Dear Andre',
thanks for your reply. I disabled reverse debugging but this didn't have
any effect for the local variable display.
As soon as I add a local variable from the stack to the "local variable
window" I get the following message:
for Qt Creator 2.0.1: "<invalid> <unknown>"
for Qt Creator 2.1.0: <no such value>
The debugger log says the following when adding a variable "pMainLayout"
to the "local variable window":

I am using gdb 7.2 right now.
As far as I can see this only happens for local variables in constructors
of my classes. In member functions the locals get displayed properly.
Any comments on this?
Best regards,
