I think there is an alternative method that will achieve the same result,
but without affecting Cygnus/FSF sources.
We can add a replacement function for
void ***
__get_dynamic_handler_chain ()
{
return &__dynamic_handler_chain;
}
to libc_r that can do this:
void ***
__get_dynamic_handler_chain ()
{
return &_thread_run->dynamic_handler_chain;
}
I guess that I must be missing something here. Seems simple.
