QtSingleApplication on Windows

[RafalNiewinski]

Hi, I have a problem with QtSingleApplication of a set of Qt Solutions.
When I run the application, there is a segfault.
I wrote an application mainly on Linux without problems.
I decided to compile a version for Windows and now here's the problem.

The application dies at run of constructor:

QtSingleApplication(argc, argv)

Maybe someone has a solution ?

With that information we can't say anything. Debug it and post the backtrace.

Sorry for the long response time and for any deficiencies in the earlier posts (was in a hurry).

I did a dump of debug and it turns out that the problem occurs in place where an object of type QColor in StyleHelper is creating.

Backtrace:

I noticed that the problem occurs only when compiling with mingw. When compile with MSVC everything works fine.

Can you post the relevant parts of the backtrace.
