Subject: [PATCH] More test case for r208715.

The commit r208166 will cause some regression on ARM EHABI.
This fix has been committed in r208715, and an assertion failure
test case has been committed in r208770.

This commit further extends the unittest so that the actual
value in the handlerdata will be checked.
