New issue 2388: Sandbox broken in 5.4.0 os.access() called with float mode
https://bitbucket.org/pypy/pypy/issues/2388/sandbox-broken-in-540-osaccess-called-with
Stefano Rivera:
The sandbox fails to get to a REPL in 5.4.0, it seems something is making a
broken call to `os.access()` with a floating point `mode` argument:
```
[sandlib:call] ll_os.ll_os_getenv('PYPY_GENERATIONGC_NURSERY')
[sandlib:result] None
[sandlib:call] ll_os.ll_os_getenv('PYPY_GC_DEBUG')
[sandlib:result] None
[sandlib:call] ll_os.ll_os_envitems()
[sandlib:result] []
[sandlib:call] ll_os.ll_os_stat('/bin/pypy-c')
[sandlib:vpath] '/bin/pypy-c' => <RealFile
/usr/lib/pypy-sandbox/x86_64-linux-gnu/pypy-c-sandbox>
[sandlib:result] posix.stat_result(st...ctime=0)
[sandlib:call] ll_os.ll_os_access('/bin/pypy-c', 1.0)
[sandlib:vpath] '/bin/pypy-c' => <RealFile
/usr/lib/pypy-sandbox/x86_64-linux-gnu/pypy-c-sandbox>
