[making initializer functions static]
> Why is this necessary if we use Jason's patch?
Because of the example that triggered the whole thread: You use two
shared libraries which both have the same global function. Ian Taylor
tells me that this is legal and standard use, despite its violating
the odr. People do such things with shared libraries.
Now, you create global objects in each shared library, which are keyed
to the global function. The dynamic linker will then initialize one
object twice, and the other not-at-all.
If we think this is legal use, we should fix the problem.
Regards,
Martin
