You start by reading the line the error was reported on:
R->fp = open(datafilename, O_RDWR | O_CREAT);
the bug is obvious - open with O_CREAT among flags must be given
3 arguments.
glibc recently added for -D_FORTIFY_SOURCE=2 error checking
open/open64/openat/openat64 macros that verify proper use, since
many people make mistakes with it.

Alternatively you could have searched the headers for
__open_missing_mode:
...
/* If the compiler complains about the size of this array type the \
mode parameter is missing since O_CREAT has been used. */ \
typedef int __open_missing_mode[((flags) & O_CREAT) != 0 \
? ((long int) sizeof (___arr) \
- (long int) sizeof (int)) : 1]; \
...
and the comment says it all (similarly for other errors the new
open macro can report, such as more than 3 arguments or invalid type
of the last argument).
