1. For now, I will just include the patch:
diff -r1.170 tree-inline.c
1249a1250

1250a1252,1253

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:

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.
