I'm a bit confused. Do you mean the following? * The current implementation of rtld has a problem both with libpthread and libthr. It works only with libc_r. * In libpthread case, the problem goes away if we modify rtld code. * In libthr case, in addition to above, we must modify libthr code to provide implementation of the locks for rtld. right? -- Kazuaki Oda _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
