[8.5.2] Custom compiler problem

I have a hierarchy of classes which use a custom compiler. Filing in new code is not a problem, the alternate compiler works as expected.

However, when browsing differences and loading alternatives (i.e., the previous version), I get an error. The error arises because the system needs to recompile the method, but my custom compiler requires a class method to be present. The image builder shows that the class methods should be there, but it hasn't installed them in the new instance of the class that it is creating. The class methods are seemingly ignored by EmImageBuilder class>>#createMethodFrom:in:orLink: answering false very early.

A related issue is that the method edition decides whether to use the linker based on whether the standard compiler is being used. (See EmMethodEdition>>#useLinkerFor:) It seems to me that this is incorrect, as I don't see anything in my method instances which suggest recompilation is necessary.


Any advice or guidance would be appreciated.
Thanks.

I will add further that the problem seems to have arisen from the Load Alternatives selection applied against the class rather than the individual methods. I have not verified this, however.
