I've been using GDB for a few months now, and suddenly I've got this
problem: when I start GDB from the command line and specify an object
file, such as "gdb testprog", I get this message:

Reading symbol data from /tmp/testprog...gdb: virtual memory exhausted.

I own the file "testprog", it has global permissions, it has been
compiled with gcc 1.39 using the -g flag, etc.  This problem is not
specific to this program, either; I've tried about 15 other objects, and
all produce the same error.  I figure it's got to be something
unbelieveably simple, since I'm running the same version of GDB as
always - it hasn't even been recompiled.

For the record, my system is an Intel 486-25, with 8MB of RAM and two
330 MB ESDI disks, running SCO V.3.2.2.

Can anyone make heads or tails of this?  Thanks much.
