# To do this, we must shutdown the currently running gdb and restart

# with the -core args.  We can't use gdb_start because it looks for

# the first gdb prompt, and the message we are looking for occurs

# before the first prompt.

# Another problem is that on some systems (solaris for example), there

# is apparently a limit on the length of a fully specified path to

# the coremaker executable, at about 80 chars.  For this case, consider

# it a pass, but note that the program name is bad.
