Armin Rigo:

If libpypy-c.so was loaded with ``dlopen()`` instead of by the dynamic linker when the program starts, then x86/assembler.py will produce wrong code (or crash in an assertion error) in ``threadlocalref_get()``.  This is because the handling of thread-local variables is rather messy on Linux.

One easy workaround is to load your main program with ``LD_PRELOAD=...libpypy-c.so``.  Obviously, it would be a better idea to find a proper fix.
