------- Comment #1 from rguenth at gcc dot gnu dot org 2008-01-25 10:06 -------
We ICE in verify_cgraph because at the time we dump the call stmt here:
#5 0x0000000000b9d3ec in verify_cgraph_node (node=0x2af3434e1e00)
at /space/rguenther/src/svn/trunk/gcc/cgraphunit.c:800
800 debug_generic_stmt (e->call_stmt);
(gdb) l
795 if (!e->aux)
796 {
797 error ("edge %s->%s has no corresponding call_stmt",
798 cgraph_node_name (e->caller),
799 cgraph_node_name (e->callee));
800 debug_generic_stmt (e->call_stmt);
801 error_found = true;
cfun is NULL.
P2 as a broken cgraph leads to further problems and this is undiagnosed
without checking enabled.
At least until this is investigated further. Honza?
