Greetings!

There is a bug suspicion, and I wanted to report it by the following example.

https://godbolt.org/z/m6g3Ug  

GCCs 9.x and older inline capturing lambdas for the case in example even on -O1
GCC 10.1 always inlines only on -O3. On -O2 inlines it only if capturing lambda
is called < 3 times in a row.


Best regards, Leonid.
