Author: kwm Date: Tue Feb 19 16:24:16 2013 New Revision: 312583 URL: http://svnweb.freebsd.org/changeset/ports/312583 Log: Add workaround for when clang is used as a compiler, due to a tail calls optimization bug in llvm when PIC mode is used. This bug was reproduced with 3.2 and 3.1 on i386. And prevents modules that where dlopen()'d by the xorg-server, to dlopen() other shared modules by themself. This is known to happen with the vmware and vesa drivers others might be affected.
