bug#13258: bug in ln.

[Joshua Rogers]

ln bug.

$ gdb ln
GNU gdb (Ubuntu/Linaro 7.4-2012.04-0ubuntu2.1) 7.4-2012.04

Reading symbols from /bin/ln...(no debugging symbols found)...done.
(gdb) run `perl -e 'print "x"x(2**31)'` `perl -e 'print "x"x(2**30)'`
Starting program: /bin/ln `perl -e 'print "x"x(2**31)'` `perl -e 'print
"x"x(2**30)'`
/bin/bash: xrealloc: ../bash/subst.c:5179: cannot allocate
18446744071562067968 bytes (4295012352 bytes allocated)
During startup program exited with code 2.




Doing it without gdb, it just crashes the console.
Inside `screen` it crashes that one screen (say you have two "tabs" in
the screen, it only crashes the one tab)
Bug can be reproduced like this:
/bin/ln `perl -e 'print "x"x(2**31)'` `perl -e 'print "x"x(2**30)'`


K, thanks.
