>Description:

  Consider the following (ill-formed) script:

--- cut ---
#!/bin/sh

echo "abc" | \
	{ \
	}
--- cut ---

  Trying to run it yields:

	$ sh x.sh
	[1]   Segmentation fault (core dumped) sh x.sh

  The backtrace is as follows:

(gdb) bt
#0  0x0804cd22 in prehash ()
#1  0x0804bb9b in evalpipe ()
#2  0x0804b5d2 in evaltree ()
#3  0x08054642 in cmdloop ()
#4  0x080543b3 in main ()
#5  0x08049da6 in ___start ()
