Memory leak issue?

[shawn-digitalpoint]

When updating MadelineProto via composer, it runs out of memory when transpiling (for PHP 7.4).

Tried overriding Composer to use 2GB and got farther, but didn't complete. 4GB still wasn't enough. Ended up giving Composer 10GB to work around it and get through the update process.
