I started to see a new failure on my nightly amd64-unknown-freebsd8.0 tester:
/scratch/tmp/gerald/gcc-HEAD/gcc/cp/pt.c: In function ‘tree_node*
maybe_get_template_decl_from_type_decl(tree)’:
/scratch/tmp/gerald/gcc-HEAD/gcc/cp/pt.c:7064:1: internal compiler error: in
propagate_threaded_block_debug_into, at tree-ssa-threadedge.c:623
maybe_get_template_decl_from_type_decl (tree decl)
^
This happens in stage3-bubble.
