SIGSEGV in debugging mode only

[Dimidroll93]

My environment is:

bq.
Windows 8 x64
Qt Creator 3.3.0,Based on Qt 5.4.0 (MSVC 2010, 32 bit), Built on Dec 8 2014 at 15:24:21, From revision d36c4d87db
MinGW 4.9.1
GDB debugger used

I wrote a simple program to import function from dll. When I starting in debuging mode, I have SIGSEGV i.e. Segmentation fault, when imported function is called. But when program is started in Run mode, all works normally.

Thereby, I can't debug my program. Any one solved this issue?

I read "related topics":http://qt-project.org/forums/viewthread/19682http://qt-project.org/forums/viewthread/19682 , "and ":http://qt-project.org/forums/viewthread/18974

I have no any internet security services and antiviruses. I stronly sure external function works properly.
The main question is "How to start program in debug mode with no segmentation fault?".

Hi,

You might be hitting an assert somewhere, are you sure you are calling that function properly ?

Yes, I checked the pointer to function. I can't understand why program works fine without debugger, and It crashes in debugger mode.

With no debugger mode, imported function returns data as expected.

I meant an assert in the library you are using

I have no sources for external library. I using this library from MSVS and have not any questions.
I think it's matter in differences debug / no debug modes.
