[Bug c/39406] New: ice in tree-dfa.c for legal code with -O2

[dcb314 at hotmail dot com]

I just tried to compile the Suse Linux package sparse sparse-0.4.1.git1-1.56
with the GNU C compiler version 4.4 snapshot 20090306
and the compiler said

sparse.c: In function 'check_context':
sparse.c:546: internal compiler error: in referenced_var_lookup, at
tree-dfa.c:563
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O2 required.
