6l doesn't detect dependency cycles #2052
Description
What steps will reproduce the problem? 1. Make a package X. 2. Write another package Y that (perhaps transitively) depends on X. 3. Write a test for package X that depends on Y, and have that test be in package X (i.e. not in package X_test). 4. Build and run the test. What is the expected output? 6l should refuse to link the test due to the cycle. What do you see instead? One of two things: - 6l refuses to link the test due to "linker skew", or - 6l links the test, and the resultant test binary ends up initialising package X twice. Which compiler are you using (5g, 6g, 8g, gccgo)? 6g/6l. Which operating system are you using? Linux. Which revision are you using? (hg identify) weekly.2011-06-16 (but it's been around since March)
