oldiofclose.c and segmentation faults

Hi,

I was wondering if someone had thoughts on a segmentation fault I have been getting. This code was not written by me - I'm just working on it now. I've stepped through the program using the gdb debugger, and I'm getting this message:

Program received signal SIGSEGV, Segmentation fault.
0x00ba6f6b in _IO_old_fclose (fp=0x83d1e68) at
oldiofclose.c:60
60 oldiofclose.c: No such file or directory.
in oldiofclose.c
(gdb)

That's the last (and only) error. I think the program is generating this error while writing to a bunch of output files. My question is this: according to a Google search, this problem is caused by a compilation problem. Basically, you need to compile against glibc 2.1.1 (or higher). I'm looking into that aspect of it now, but does anyone know of any OTHER reason I could be getting this error?

Thanks in advance.

The error suggests that fclose is being called with an invalid argument (a value not returned by fopen or a value that has already been passed to fclose).
