[Bug tree-optimization/27474] New: ICE: tree check: expected ssa_name, have struct_field_tag in verify_ssa, at tree-ssa.c:776

Sun, 07 May 2006 12:29:43 -0700 

This ICE happens during compilation of PovRay-3.6.1 with -msse2
-ftree-vectorize (also on x86_64). The ICE is in express.cpp.

The reduced testcase is attached, this is the failure with -O -ftree-vectorize:
g++ -O -ftree-vectorize -m32 -msse2 reduced.cpp
reduced.cpp: In function ‘void pov::Parse_Num_Factor(double*, int*)’:
reduced.cpp:94: internal compiler error: tree check: expected ssa_name, have
struct_field_tag in verify_ssa, at tree-ssa.c:776
Please submit a full bug report,
[etc]

The same failure happens with g++ -O -ftree-vectorize on x86_64.
