Author: kib Date: Wed Jul 31 19:27:20 2019 New Revision: 350481 URL: https://svnweb.freebsd.org/changeset/base/350481 Log: Avoid conflicts with libc symbols in libthr jump table. In some corner cases of static linking and unexpected libraries order on the linker command line, libc symbol might preempt the same libthr symbol, in which case libthr jump table points back to libc causing either infinite recursion or loop. Handle all of such symbols by using private libthr names for them, ensuring that the right pointers are installed into the table.
