When max_files_per_process=1201 or more server not start. I tested and
debugged this on Windows 7. On Windows 10 work all right.
I found this take place after call function count_usable_fds(int
max_to_probe, int *usable_fds, int *already_open)
Error occured on the first call selres = select(nSockets, &rmask, NULL,
NULL, &timeout) from ServerLoop. Error 0xC0000142: "{DLL Initialization
Failed} Initialization of the dynamic link library %hs failed. The
process is terminating abnormally."
I temporarily moved call set_max_safe_fds() to top of the PostmasterMain
and error moved to ReadFile in function pipe_read_line(char *cmd, char
*line, int maxsize):
if (!ReadFile(childstdoutrddup, lineptr, maxsize - (lineptr - line),
&bytesread, NULL))
Repeat the error in a separate example did not work yet.
Replacing dup for stdin on dup of file handle resolve this problem.

Using dup (0) in the function count_usable_fds more than 1200 times (0 =
stdin) causes further unpredictable errors with file operations.
Could you expand a bit on this?
