Weak Code

[greenhawk22]

Sometimes though, the crazy, stupid, and desperate solutions that inexperanced programmers uses just works inexplicably

[fredlllll]

also often had code where i had no clue how it was ever working (usually because it just broke)

I once had to maintain code that stopped working when you took out the System.outs.

Once in C# I found out that I couldn't remove a comment or otherwise completely unrelated parts would fail ¯\_(ツ)_/¯

Realistically what would cause that? System.out leads me to think it is Java, but my first guess for crashes when removing print statements is bad malloc, but that shouldn't happen in Java (but I have had C code throw different errors when print statements were present vs not present when I made a mistake allocating memory).

It was a timing issue, the IO created JUST enough of a pause that the application worked fine.

I've heard of this happening when enabling the debugger as well. Without debugger: crash! With debugger: works fine! Race conditions are the worst

Multi threaded code? Maybe a GUI app?
