glass bed

Highly unlikely. This might occur only if you could secure the glass completely along all four edge with zero possible movement.
As most glass plates are secured at corners or with a weak adhesive or tape on the corners - and as glass has a really low expansion coefficient anyway - it's pretty much never goiung to be an issue.

I used cheap poundshop picture frame glass with no problems for a while.
I much prefer my current aluminium bed. But as I pretty much just print on gluestick now - as long as the bed is flat the actual bed material is largely irrelevant.

Repeated heat cycles will destroy regular glass regardless of how it's attached to the bed.
