[issue18551] child_exec() doesn't check return value of fcntl()

[Christian Heimes]

New submission from Christian Heimes:

http://hg.python.org/cpython/file/96d817f41c4c/Modules/_posixsubprocess.c#l384

CID 715330 (#2 of 2): Unchecked return value from library (CHECKED_RETURN)
17. check_return: Calling function "fcntl(c2pwrite, 2, old & 0xfffffffffffffffe)" without checking return value. This library function may fail and return an error code.

Could this cause any kind of trouble or shall I dismiss the issue as intentional?
