Relocation completes for all objects, and only then ELF constructors are invoked. This two-pass approach is necessary because otherwise, it would be more likely that unrelocated code is executed if symbol interposition or underlinking is in play. If you want to run your own code before relocation processing, you should look at LD_AUDIT and audit modules. The Solaris documentation mostly applies to glibc as well, at least as far as the basics are concerned. Thanks, Florian
