[Qt-creator] Debugging fails with QtCreator

[Jochen Becher]

Hi Orgad,

thank you for that information. Hm, it is not that easy to downgrade gdb
to 7.6. Ubuntu 14.04 is not proving that version and I couldn't find any
repository that provides it.

I assume I have to compile gdb 7.6 from source. Will see how that works.

Regards, Jochen
