This can cause some weird side effects, which in turn can lead to memory corruption. You can read the full report with a detailed description and test program at http://www.freebsd.org/cgi/query-pr.cgi?pr=ports/120052 Attached is the submitted patch, which fixes the issue. Regards Marcus

The reason these libraries are built outside of the standard XFree86
tree is so that they can be linked as shared object code directly into
SDL without causing any symbol collisions with code in the application.

You can't link static library code into shared libraries on non-x86
Linux platforms.  Since these libraries haven't become standard yet,
we'll just include them directly.

These sources are synchronized with XFree86 4.2.1
