[issue17531] test_grp and test_pwd fail with 32-bit builds on OS X systems

[Ned Deily]

Ned Deily added the comment:

That fixes the test for nobody (-2). Now the next part of the test fails more seriously for nogroup (-1).  Simplifying:

2.7.3
$ arch -i386 /usr/local/bin/python2.7 -c 'import grp; g=grp.getgrnam("nogroup").gr_gid; print(grp.getgrgid(g),type(g))'
(grp.struct_group(gr_name='nogroup', gr_passwd='*', gr_gid=-1, gr_mem=[]), <type 'int'>)
$ arch -x86_64 /usr/local/bin/python2.7 -c 'import grp; g=grp.getgrnam("nogroup").gr_gid; print(grp.getgrgid(g),type(g))'
(grp.struct_group(gr_name='nogroup', gr_passwd='*', gr_gid=4294967295, gr_mem=[]), <type 'int'>)

2.7.4rc1:
$ arch -i386 /usr/local/bin/python2.7 -c 'import grp; g=grp.getgrnam("nogroup").gr_gid; print(grp.getgrgid(g),type(g))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
OverflowError: group id is greater than maximum
$ arch -x86_64 /usr/local/bin/python2.7 -c 'import grp; g=grp.getgrnam("nogroup").gr_gid; print(grp.getgrgid(g),type(g))'
(grp.struct_group(gr_name='nogroup', gr_passwd='*', gr_gid=4294967295, gr_mem=[]), <type 'int'>)
