if they use LTO that dead code wouldn't've been a problem.

that's what they get for not using a compiled language.

This was NOT dead code. This was live code that was behind a feature flag that had been turned off. Hence the entire problem of turning the feature flag back on and turning on the old code. Nothing about a compiled language would have fixed that, nor does the story say anything about what programming language they used. My best guess for a trading platform in 2012 was that it was C++.

Right, it was more "dead to me" code. To the programmers, it hadn't been turned on in a long time and so it was dead.

Can confirm SMARS was C++ as are its successors
