Fwd: [KTechLab] [Bug 473717] New: Application crashes on adding a subcircuit

[Zoltan Padrah]

FYI,

apparently KTechLab 0.51.0 might crash when using subcircuits.
Release 0.50.0 is not affected.
Fix is in git master [1]
Testing is welcome :-)

The crash is introduced by the modernistaion of signals/slots mechanism,
where a C++ lambda has been introduced, and I assume that those changes
interfere with some object lifetime.

Have fun,

Subcircuit that causes crash

SUMMARY
Ktechlab crashes when I try to add a custom subcircuit to another circuit.
This
started happening this week, it was working without problems before. This
only
happens with custom subcircuits and not the default ones.

STEPS TO REPRODUCE
1.  Create a custom sub circuit.
2.  Add it to another circuit.

OBSERVED RESULT
Program crashes with sigfault.

EXPECTED RESULT
Use subcircuit without problems.
