Masayuki, can you take a look at what's up here? Could it be related with some TSFTextStore changes landed in the past months?

Well, that could be caused by our changes. However, the crash is a null pointer reference in IME. Unless we forget to guarantee the lifetime of our own objects, this is a bug in the IME. Additionally, TSF may have been updated by Microsoft. So, this could be caused by some changes on Windows too. I think we can do nothing for now.

Note that Google Pinyin input has already been discontinued at least 5 years ago. So, the crash bug won't be fixed by Google. If Mozilla thinks the crash rate is too high, we can reject to load the IME in our process. See bug 1409155.

In these 3 months, the share of 谷歌拼音输入法 2 and 谷歌拼音输入法 3 in all Simplified Chinese IME users on Firefox is about 0.2% (counted in main_1pct).
