1. For now, I will just include the patch:

diff -r1.170 tree-inline.c
1249a1250

1252d1254
<     case TARGET_EXPR:

2. However, it seems that as of Mar 18 CVS, the crash no longer occurs.
This is probably because of this change:

Fri Mar 18 10:00:16 2005 UTC  by hubicka
	PR middle-end/20225
	* cgraph.c (cgraph_mark_reachable_node): Assert that it is not called
	too late.
	* varasm.c (find_decl_and_mark_needed): Mark needed only when not
	called too late.

3. This patch might be reversed:

If the regression returns, I will try to find --param options that cause 
the ICE on a clean tree.
