[Bug tree-optimization/42703] New: [4.5 Regression] ICE in generate_subtree_copies, at tree-sra.c:2003

[doko at ubuntu dot com]

seen with trunk 20100107, not with the 4.4 branch. lowering optimization to -O0
lets the build succeed.

$ gcc -c -O1 uvector.i 
uvector.c: In function 'swapb64':
uvector.c:10935:1: internal compiler error: in generate_subtree_copies, at
tree-sra.c:2003
Please submit a full bug report,
with preprocessed source if appropriate.
