That is, until I started writing Wasm code – not compiling for Wasm, but writing the instructions by hand. And I found out that there exists a major difference between Wasm and all…
Some time ago, I played around with decompiling Java class files in a more efficient manner than traditional solutions like Vineflower allow. Eventually, I wrote an article on my approach to decompiling control flow, which was a great performance boost for my prototype. At the time, I believed that this method can be…

As compiler optimizations, intuitive but incorrect simplifications, and platform-specific quirks have piled on, the odds of making a wrong assumption have increased, leading to the proliferation of bugs and vulnerabilities.

Even though it’s a catchy title, panics are hardly suited for this goal, even if you try to hack around with macros and libraries. The real star is the unwinding mechanism, which powers panics. This post is the first in a series…
