New issue 2795 by [email protected]: Check fails with deopt for mjsunit/array-store-and-grow
http://code.google.com/p/v8/issues/detail?id=2795

Check fails when using deopt-every-n-times flag. Tested with revision 15821. Please analyze if the test case makes sense to be used with the deopt-every-n-times flag.

Command line:

out/ia32.debug/d8 --test --deopt-every-n-times 2004567 --nobreak-on-abort --nodead-code-elimination --nofold-constants --enable-slow-asserts --debug-code --verify-heap --noparallel-recompilation test/mjsunit/mjsunit.js test/mjsunit/array-store-and-grow.js

Output (shortened):

#
# Fatal error in ../src/objects-inl.h, line 2555
# CHECK(object->IsSmi()) failed
#
