I keep forgetting the fact that debug build crashes because ASSERT calls CRASH, and it will not crash release build, sorry about that.

Given that, and that purgeInactiveFontData() isn't on this code path as of now, I wonder this may not be important enough to fix.

The fix has a risk to introduce a new problem because ~FontCachePurgePreventer() may call purgeInactiveFontDataIfNeeded(), so if its callers are not preventing purging and assuming no one calls purgeInactiveFontData(), their data may be purged. I looked for source files and seems safe to me, but didn't look all ports.

Since I don't have good idea how we want to handle possible issues like this (ASSERT only, no actual harm,) will someone please advice? I'm fine with WONTFIX if the someone thinks so.
