Big types and memory consumption when profiling
Summary
I have an application with a large data type (more than a hundred records).
If I enable profiling, GHC 8.8.2 takes a huge amount of memory and time to compile the module containing the sole aeson instances. Generic shouldn't be the culprit since the instances are non-empty.
After 1 hour and 60G of memory consumed, I can't tell the total amount of memory required, because I'm forced to end the process for lack of space for the swap file.
Steps to reproduce
Create a datatype with a hundred records (mostly Text and Int, strict and packed) and both the instances FromJson and ToJson.
Build with stack build --profile.
Environment
GHC 8.8.2 and stack.
