Description:
------------
file ext/standard/file.c
line 1028
buf = ecalloc(len + 1, sizeof(char));
if (php_stream_get_line(stream, buf, len, &line_len) == NULL) {
goto exit_failed;
}
here doesn't check the availablity of 'buf', so if ecalloc doesn't
calloc a memory, it will return NULL, it will cause some problem
Reproduce code:
---------------
$fp=fopen("1.txt", "r");
fgets($fp, 2147483640);
on some platform, when ecalloc failed, it will return NULL, so
segmentation fault will prompt.
the same as fread function
