It ends up making two similar types, [N]uint8 of both alg and noalg varieties. Comparsions between the two then don't come out equal when they should. In particular, the type *[N]uint8 has an Elem pointer which must point to one of the above two types; it can't point to both. Thus allocating a *[N]uint8 and dereferencing it might be a different type than a [N]uint8. The fix is easy. Making a small test for this is really hard. It requires that both a argless defer and the test be imported by a common parent package. This is why a main binary doesn't see this issue, but a test does (as Agniva noticed), because there's a wrapper package that imports both the test and the defer. Types like [N]uint8 don't really need to be marked noalg anyway, as the generated code (if any) will be shared among all vanilla memory types of the same size.

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.
To run just these tests, execute:
../bin/go run run.go
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:
- it is most naturally expressed using the test runner; or
- it is also applicable to
gccgoand other Go tool chains.
