Alternatively, if one really wants to keep the data in memory, one can use the identity precompile to copy from memory to memory. It should be cheaper if that loop...

``` (seq p = x * y p1 = mulmod(x, y, not(0)) assert(p == p1) x*y ) ``` If `x * y = not(0)`, this won't be true, right? For...

Unfortunately, changing to `>=` won't help either. Take `x = 2**256 - 1` and `y = 2`, then `x * y` overflows and evaluates to `2**256 - 2`, but `mulmod(x,...

Here's a before and after before: https://output.circle-artifacts.com/output/job/1839fe06-7445-49a1-8622-48d9d78cb87d/artifacts/0/docs-html/introduction-to-smart-contracts.html after: https://output.circle-artifacts.com/output/job/27a7a6be-0d7f-4fca-b30f-1d1bb13e06f8/artifacts/0/docs-html/introduction-to-smart-contracts.html Somewhat indifferent on the change. Maybe @franzihei has an opinion here. Also, PR number 👀

Unfortunately, this is a known issue, and does not have a good fix. (We are working on a solution for upcoming solidity versions, but until then, sorry) Here are two...

@SvenMeyer Could you post a minimal example with the stack too deep error? Perhaps we could help with a specific suggestion to fix it. BTW, the function `getPurchaseStruct` is redundant...

@SvenMeyer In 0.8.0, `abi encoder v2` is enabled by default, please check the release notes.

@lepidotteri OVM is a project independent of solidity. AFAIK, OVM currently doesn't support 0.8.*. Please ask them directly about the status.

> My only question now is what the effect of disabling the YUL optimizer will be. @cliffhall The ABI encoder v2 code for your contract would not be optimized.
