Just want to add this to the ""funny"" answers about cracked glass.
Maybe some are just joking about safety but I think that we are never too prudent when burning a stove.
A gap intentionnally made at the top or bottom of a stove's glass in one thing and a no-problem and has no link with a cracked or damaged glass.
Serious stoves makers like : Vermont Castings, Harman Stoves and many more write in the owner's manual: ""If a glass is broken or damaged, do not operate the stove until it has been replaced"", from Harman Stoves TLC 2000 manual, Section Operation, P.8

The supports/brackets holding the glass/es in place must not be too tight. If so stress can occur in the glass/es and cause a damage to it.
Plus in the event a glass needs to be change, taking the screws out will be easier. Why having a glass too tight when we ""all"" know that many stoves makers provide an air gap at the top or bottom of the glass :?:

I had the local glass etc place put a replacement in. They called me 45 minutes after I dropped it off to tell me it was done. One Ben Franklin later and I'm back in business. I took the lame way out and fired her back up with matchlight. She's back in action and the house is warm again. Thanks for listening :)

My Efel Kaminar had around 20+ vertical glass strips, even beveled at the corners (like a bay window) When cold, the additive gap among all the strips was easily 3/8". When hot, they expanded a bit, but still they were loose and ill-fitting, when cleaning them they would slide around. It worked like this for 24 years, never a problem. So I'd say it was like having 20+ cracks in my glass.

I guess it turned into over-fire air, always being a negative pressure in the firebox? I say ignore the crack, no rush to repair.

Just sayin...

Oops. A couple days late and a Ben Franklin short. The story of my life...
