Re: Odd ld behaviour starting at version 2.22

If you have a look at the ld/NEWS file in the sources you can see what 
changed with the introduction of release 2.22.  One item stands out:

  * --copy-dt-needed-entries is no longer enabled by default.  Instead
    --no-copy-dt-needed-entries is the default.

Maybe if you try adding -Wl,--copy-dt-needed-entries to your g++ command 
line you will get a different behaviour ?  (Just a guess, but worth a try).

Are all the symptoms related to startup/shutdown code ?  If so then the 
problem could be related to the linker script used to combine all the 
object files and libraries together.  How about linking with the 2.21 
linker script but using the 2.24 linker ?


Just a couple of ideas.
