Oh, yes that's right. I didn't notice the attribute came from a Debian patch
meant to be dropped.
The problem with the function as it is, is that by calling cthread_getspecific
it forces dlerror to clobber errno; and then the console client is in trouble.
May I do as below?
void *val = NULL;
if ( _cthread_init_routine)
cthread_getspecific (key, &val);
return val;
Thanks,
Diego
