GDAL Application crashes when loading GDAL drivers

[المشرف العام]

I'm developing on QT an application that uses GDAL library (which I compiled using MinGW 4.8). When I use the application on my windows 8 laptop, it works fine, but when I tried using it on several windows 7 computers it crashes as soon as I use the GDAL dll.

Mapper::Mapper() {
GDALAllRegister();
...
}

​

My program didn't send any error, but when I looked in the eventlog I saw this:

Faulting application name: MainApp.exe, version: 0.0.0.0, time stamp: 0x00000000

Any ideas what may be causing this?
