Summary: "Unable to coalesce ssa_names <x> and <y>" ICE in
tree-ssa-coalesce.c when -O3 is used
Product: gcc
Version: 4.4.6
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassig...@gcc.gnu.org

This is the input file to the compiler that produces an ICE.
To reproduce, use the attached file and run:
g++ -o /dev/null -S -O3 reduced.manual.inline.cc
You will get this message:
Unable to coalesce ssa_names <x> and <y> which are marked as MUST COALESCE.
This is reproducible with the latest (as of Jan 20th, 2011) 4-4 branch of gcc.
It seems to not happen with the trunk.
