glDeleteTextures not deleting texture

I'm trying to write a class to do fragment shader chaining by using a Frame Buffer Object to Render To Texture with a frament shader, then render that texture to another texture with a fragment shader, etc. etc.

I am trying to deal with a memory leak right now, where when I resize my window and delete/reallocate the textures I am using, the textures are not being deleted properly.

Here is a code snippet:

//Allocate first texture
glGenTextures( 1, &texIds[0] );
glBindTexture( GL_TEXTURE_2D, texIds[0] );
glTe开发者_C百科xImage2D( GL_TEXTURE_2D, 0, GL_RGBA8, screenX, screenY, 0, GL_BGRA, GL_UNSIGNED_BYTE, NULL );

//Allocate second texture
glGenTextures( 1, &texIds[1] );
glBindTexture( GL_TEXTURE_2D, texIds[1] );
glTexImage2D( GL_TEXTURE_2D, 0, GL_RGBA8, screenX, screenY, 0, GL_BGRA, GL_UNSIGNED_BYTE, NULL );

//Try to free first texture -- ALWAYS FAILS
glDeleteTextures( 1, &texIds[0] );
//Try to free second texture
glDeleteTextures( 1, &texIds[1] );

When I run this with gDEBugger, it tells me "Warning: The debugged program delete a texture that does not exist. Texture name: 1" when I try to delete texIds[0]. (The reason I have them in an array right now is because I used to creating and free'ing them at the same time, however when you free 2 textures at once, it will fail silently on one and continue with the other).

If I don't create texIds[1], I can free texIds[0], but as soon as I create a second texture, I can no longer free the first texture I create. Any ideas?

Perhaps the error is in texIds array. Is it array of GLUint?

You could erroneously declare it as array of word, thus when generating texture for [1] element, uint pointer taken from element [0] is broken.
