Hi,
I have problem with glFramebufferTexture2DEXT function with intel GMA4500MHD 7.15.10.1688 drivers (using vista 32 bit). I'm attaching sample project which demonstrate failure (exception):
[cpp]First-chance exception at 0x10053930 in enum.exe: 0xC0000005: Access violation reading location 0xfeeeff86.
Unhandled exception at 0x10053930 in enum.exe: 0xC0000005: Access violation reading location 0xfeeeff86.[/cpp]
The code throw exception in enum.cpp on line 109:
[cpp]glDeleteTextures(1, &tid); // <--Crash--[/cpp]

If line 102 in the enum.cpp file 
[cpp]glTexImage2D(target, 0, fmt, prob_size, prob_size, 0, GL_RGBA, GL_UNSIGNED_BYTE, 0);

with comment "// <--Here--" is commented, no exception is thrown.
