Hi Yang,
Thanks for the review and have a try to modify the old space size. I did not
change anything. Here is the crash trace in my machine:
#
# Fatal error in ../src/contexts.h, line 236
# CHECK(context->IsContext()) failed

The crash happens in the bootstrap. The function ClearJSFunctionResultCaches
assumes native_contexts_list_ is not NULL, but native_contexts_list_ is set
to
undefined_value() after CreateInitialObjects in the CreateHeapObjects. I
tried
to modify ClearJSFunctionResultCaches to see whether context (heap.cc:832)is
NULL, but it crashes elsewhere.
Considering https://chromiumcodereview.appspot.com/10533148, it might make
sense
to add 4K more memory for this test case. I do not know why this is not
caught
by your trybots and could not be reproduced on your machine.
