[pypy-dev] Pypy-2.1-beta2 translation error

Hi, While trying to self-translate pypy-2.1-beta2 I got the following error: RPython traceback: File "rpython_jit_metainterp_resume.c", line 7778, in blackhole_from_resumedata File "rpython_jit_metainterp_resume.c", line 9972, in ResumeDataDirectReader_consume_vref_and_vable File "rpython_jit_metainterp_resume.c", line 695, in ResumeDataDirectReader_consume_vable_info Fatal RPython error: AssertionError Is this a known problem or something wrong with my setup?
