Having trouble with Ada programs using calls to textio and other
standard io functions.  Program compiles and links with no errors, but
running the program causes a segmentation fault and a core dump.  A
simple program without any io calls works just fine.  GDB returns the
following error message "Program received signal SIGSEGV, Segmentation
fault. 0x4006bf7d in _IO_setvbuf (fp=0x8070710, buf=0x0, mode=2, size=0)
at iosetvbuf.c:92. iosetvbuf.c:92: No such file or directory.

System details:
RedHat 6.0 Linux running on Intel PCs (Everything from Pentium Pro 200
to Pentium III 500)
Gnat 3.11p i686 for Linux PC running on gcc 2.8.1 included with gnat
package.
gdb 4.17.gnat.3.11p
compiled using gnatmake -f -v filename.adb -cargs -g (also tried with -a
argument added).

Any ideas what we are missing here?
Thanks.
