gcc trunk r154706
command flags: -O1 -ffast-math -floop-interchange
Running on testcase gives:

-c testcaseN2-min.i -o tmp.o
testcaseN2-min.i: In function ‘adler32’:

for SSA_NAME: sum_3 in statement:
sum_11 = adler_10 + sum_3;

Please submit a full bug report,
with preprocessed source if appropriate.

This testcase crashes in r155248, but doesn't crash anymore in r155256 (most
likely a dup of pr42185).
The original testcase (comment #1) still crashes with:
-O1 -funsafe-math-optimizations -fgraphite-identity
