6.1 crash when compiling Swift sources with -O or -Osize #80566
Description
Description
Xcode 16.3 / Swift 6.1 is no longer able to compile my code when either optimization is used (-O or -Osize) on Swift 5 Language Mode.
Since it's not proven easy to know what exactly is causing the crash (disabling compilation of the file that caused the crash would simply mean the next file in line would cause it) I am eager to learn of any techniques that would help narrow the issue down. I would love to be able to submit a reproducible case that doesn't require me submitting our entire codebase, which is not a possibility.
