glGetShaderSource doesn't zero-terminate source string

Description (last modified by frank) (diff)

This has been observed for windows and Mac OS hosts.

Once the source length (including terminator) has been established through glGetShaderiv() a buffer is allocated. The call to glGetShaderSource() is now supposed to fill this buffer with the shader source which *is* zero-terminated. The fill length is reported without said terminator (i.e. strlen(src)).

What I observe is that the length is reported correctly, the shader source itself is correct but the zero-terminator is missing.

Running the same application directly on the host GL library doesn't show the issue (i.e. the shader source is correctly terminated).

Should be fixed in SVN.
