glDeleteTextures causes segfault - c++

Question

I have this C++ console application that creates a window and initializes an OpenGL context.
IDE: CodeBocks
Compilator: MinGW (x32)
OS: Windows 8.1 64bit
So when I compile I have a console and the window with the context. When I close the window first and then the console everything is okay.
However if I close the console first I get a segmentation fault from glDeleteTextures in the virtual destructor.
Here is how I initialize the texture:
texture::texture(const string& fileName)
{
int width, height, numComponents;
unsigned char* imageData = stbi_load(fileName.c_str(), &width, &height, &numComponents, 4);
if(imageData == NULL)
cout << "Could not open " << fileName << "." << endl;
glGenTextures(1, &m_texture);
glBindTexture(GL_TEXTURE_2D, m_texture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, imageData);
glBindTexture(GL_TEXTURE, 0);
stbi_image_free(imageData);
}
void texture::useTexture(unsigned int textureUnit)
{
if(textureUnit < 0 || textureUnit > 32)
{
cout << "Texture unit not between 0 and 32. Setting it to 0..." << endl;
textureUnit = 0;
}
glActiveTexture(GL_TEXTURE0 + textureUnit);
glBindTexture(GL_TEXTURE_2D, m_texture);
}
texture::~texture()
{
glDeleteTextures(1, &m_texture);
}
Keep in mind that I wrote the same code, but compiled it with 64bit mingw and used 64bit glfw and it worked just fine... if that helps in any way.
