Unsolved Non-QT console program problem (Cannot obtain a handle to the inferior)

[wwwed]

I use QT Creator 3.5.1 (opensource). The OS is Win7 32 bit. I create non-qt console app (pure C++ console app). I compile and run it and everything is OK. Then I add new empty cpp file (using the project menu), run it again and obtain error 'Cannot obtain a handle to the inferior'. The executable exists and run, but the QT Creator can not 'hold' it.

The program is valid and has no errors.

Hi and welcome

Yes, it sounds like it is.

It happen not every time (now).
I 'stimulated' this bag in the fallowing way: I included cpp- and h-files, which contained:
inline function declaration / forward declaration (i.e. not definition) in the h-file;
inline function definition in the cpp-file.
I got the error I described above if I did not use any inlined function in the main source file. If I called any, 'unresolved reference' error appeared. And this is correct according to https://isocpp.org/wiki/faq/inline-functions .

Removal of the 'inline' keyword solved the problem. 'Unresolved...' one gone and the initial problem appears very rare (only ones this day).
