lt_dlpreload_open ... BANG!

[Bob Friesenhahn]

MinGW crashes in the mdemo test while executing lt_dlpreload_open. 
GDB reveals that the first element of preloaded_symlists contains a 
symlist with null members:

Program received signal SIGSEGV, Segmentation fault.

(gdb) bt

(gdb) p *list->symlist
$5 = {name = 0x0, address = 0x0}
(gdb) p list
$6 = (symlist_chain *) 0x3d2e10
(gdb) p preloaded_symlists
$7 = (symlist_chain *) 0x3d2e10
(gdb) p func
$8 = (lt_dlpreload_callback_func *) 0x401ac0 <loader_init_callback>

Naturally, this causes an immediate crash in streq().

Is it supposed to be possible for this condition to occur?  Why might 
this condition occur for MinGW but not for other systems?  It does 
work for Cygwin.
