I think that the problem is that fdopendir() is not defined. If a function is not defined, C uses int as the result type. An int is not enough to store a 64-bit pointer. See in gdb output: dirp is 0x0afb0e80 whereas other pointers look like 0x20973fc30. You missed the highest hexa digit (0x2).

fdopendir() requires IEEE 1003.1-2008 and so "#define _POSIX_C_SOURCE 200809L", whereas pyconfig.h defines _POSIX_C_SOURCE to 200112L (POSIX 2001).

Something should be done in configure.in, near:

  # On Tru64 Unix 4.0F, defining _XOPEN_SOURCE also requires

-----------------------------------------

I tried "AC_DEFINE(_POSIX_C_SOURCE, 200809L, Define to activate features from IEEE Stds 1003.1-2008)" but it doesn't work.

Add "#define _POSIX_C_SOURCE 200809L" at the beginning of Modules/posixmodule.c does works around this issue.
