OpenGL complains about enum usage

I've a error caught which is exactly this:

Source=DEBUG_SOURCE_API Type=DEBUG_TYPE_ERROR ID=3200 Severity=DEBUG_SEVERITY_HIGH Message=Using glGetIntegerv in a Core context with parameter <pname> and enum '0xbb1' which was removed from Core OpenGL (GL_INVALID_ENUM)
Source=DEBUG_SOURCE_API Type=DEBUG_TYPE_ERROR ID=3200 Severity=DEBUG_SEVERITY_HIGH Message=Using glGetIntegerv in a Core context with parameter <pname> and enum '0xd3b' which was removed from Core OpenGL (GL_INVALID_ENUM)
OpenGL error occured: A GLenum argument was out of range.

This is the first time this error appeared and first i thought that i'm using something which does not exist anymore but i found out that theese values do not even exist in my headers.

CLIENT_ATTRIB_STACK_DEPTH = 0xbb1
MAX_CLIENT_ATTRIB_STACK_DEPTH = 0xd3b

However after some additional research i found out that its even stranger than i thought because i have something in my code which stops the debugger in debug builds when a OpenGL error occured.

#if DEBUG
    Debug.HoldOnGLError();
#endif

This is inserted after every OpenGL call BUT it's not stopping at glGetIntegerv, its stopping at a random method mostly some glBindBufferor glBindFramebuffer.

I've no clue why does errors appear and would be happy about any idea.

Edit

Forgot to mention that the error is only appearing after some time and only in Debug mode in Visual Studio.

I found out that it's not my fault. Its fault of AMD, actually AMD-Gaming-Evolved uses old code for its overlay, thats also the reason it crashed after some time because the overlay appears after a couple of seconds.

Exiting the client solves the issue.

OpenGL debugging messages (through the callback) have been only introduced with OpenGL-4.3. The client attribute stack (glPushClientAttrib and friends) (which these enums are about) are functionality of OpenGL-1.1 and have been deprecated with OpenGL-3 and are only available in compatibility profiles. If you have a core profile context, then the relevant enums are indeed invalid to use.

Something in your program (a library or legacy code) makes use of the [client] attribute stack(s) and thereby triggers this error. You should find which part this is, because the attribute stack is being used to save and restore OpenGL state, and if the code in question relies on that to restore OpenGL state after it's done it may leave the OpenGL context in an undesired state.

The same also goes for the (server) attribute stack (glPushAttrib and friends).
