Description Danylo 2018-06-21 09:30:21 UTC 
glGetQueryiv has GL_ANY_SAMPLES_PASSED_CONSERVATIVE as a valid target and spec says:

> If pname is GL_QUERY_COUNTER_BITS, the implementation-dependent number 
> of bits used to hold the result of queries for target is returned in params. 

Now glGetQueryiv(GL_ANY_SAMPLES_PASSED_CONSERVATIVE, GL_QUERY_COUNTER_BITS, &QueryBits) produces an error.

Hello.
Case can be easy reproduced by running the test ./gl-450-query-conditional
from https://github.com/g-truc/ogl-samples

Tested with patch - test is passing now
