I'm not sure if it's a proper way to test this. The compilation is
intended to
fail but the difference is in the error messages. The correct message
is an
error in initialization line and no errors in accessing to the
variables,
incorrect - additional errors where variables are accessed.
At the moment it tests only that compiler wouldn't crash which happened
in the mentioned bug and fix proposed in
https://patchwork.freedesktop.org/series/48256/

This looks like it should be split into two different tests. Is there
any reason you included both tests together?
The reason was is that the only thing that is tested here is that Mesa
doesn't crash when compiling the shader.
Testing whether the assignment of an incompatible type produces an error
is on the other tests.
I'm not sure at this moment if that was a good reason. I can split it
into two tests if you find it necessary.
Regardless of what you are testing you still have two tests here. If
they can both trigger a segfault in different paths they should be spilt
in two. If they both test the a segfault in the same place then we
should probably simplify the test.
