Thread 19: EXC_BAD_ACCESS (code=2, address=0x70000ebf1f90) when traversing a large Syntax tree with the SyntaxVisitor in Swift Syntax. Anyone else get this? I don't know how we should or can address this...maybe it's something simple on my end.
There is a bug that caused SwiftSyntax to eat a massive amount of memory in debug mode, causing a stack overflow, especially when running on non-main thread which has smaller stack. https://bugs.swift.org/browse/SR-12360
It looked very similar to what you're experiencing now.
Are you using a recentlish version of SwiftSyntax? If not, try to update because there is a workaround written by ahoppen merged in february.
I'm using the tag for Swift 5.3.
I also had this stack overflow issue for my personal library which makes SwiftSyntax trees transmittable over JSON. I had a solution which avoided this stack overflow. Maybe similar fix could be make for the Syntax Vistor?
