[kostia.lopuhin]

New submission from kostia.lopuhin <kostia.lopuhin at gmail.com>:

Attached program crashes freshly translated PyPy (after f82ae0d (fijal, alex):
fix a crash in the JIT when memory locations are more than 4GB apart):

RPython traceback:
  File "rpython_jit_metainterp_compile.c", line 20112, in send_bridge_to_backend

It seems to be an exception here

I can reproduce it easily and give additional info
