Very low volume, the four recent crashes in nightly 70 are all in the same build on an AMD CPU with the same crash address 0x7ffed9d1f0a1 and EXCEPTION_PRIV_INSTRUCTION. I'm unfamiliar with this error, I wonder if it is an alignment issue (considering the crash address).
Some of the older ones (when aggregating all crashes in DWriteGlyphLookupCache::FillGlyphBitmap) have different crash addresses like 0x0 and also different exceptions.
At least for the recent ones it could be a bug in DWrite but the volume at this point is too low to blocklist. I don't want to be too quick to invoke The AMD Bug but at a superficial level there are intriguing similarities. I'll try to dig into a minidump if I find the time.
