Array of Range can cause an infinite loop while compiling

    • Type: Bug
    • Status: Open
    • Priority: Medium
    • Resolution: Unresolved
    • Component/s: Compiler

    • Environment:

      OSX 10.11.3 (15D21), (Swift master/f560f3caac06723, llvm stable/0d07a5d3d55078) also tested with Xcode 7.2.1

      Description

      I experienced an infinite loop in the compiler while working with `Range`s. I tried to checkout the current version (Swift master/f560f3caac06723, llvm stable/0d07a5d3d55078) and tried to understand more about it.

      Disclaimer: It's the first time I try to go deeper in this land, I'm just trying to be a bit more helpful than just reporting the bug but I might be completely wrong

      Looks like the infinite loop happens at `CSSolver.cpp:1310`and `CSSolver.cpp:1739` where `ConstraintSystem::solveRec` is calling `ConstraintSystem::solveSimplified`that again calls `ConstraintSystem::solveRec`.

      I will try to understand more but ATM I'm not experienced enough with this codebase to have proper fixes.
