# Create a core file named "corefile" rather than just "core", to

# avoid problems with sys admin types that like to regularly prune all

# Arbitrarily try setting the core size limit to "unlimited" since

# this does not hurt on systems where the command does not work and

# allows us to generate a core on systems where it does.

#

# Some systems append "core" to the name of the program; others append

# the name of the program to "core"; still others (like Linux, as of

# May 2003) create cores named "core.PID".  In the latter case, we

# could have many core files lying around, and it may be difficult to

# tell which one is ours, so let's run the program in a subdirectory.

# Test that we can simply startup with a "-core=corefile" command line arg

# and recognize that the core file is a valid, usable core file.

# 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.  Also, we can't include GDBFLAGS because

# if it is empty, this confuses gdb with an empty argument that it

# grumbles about (said grumbling currently being ignored in gdb_start).

# **FIXME**

#

# 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.
