Hi Rodrigo,

Can you explain what this web page is? It'd be helpful if this bug had a title different than "crash". It'd also be helpful to attach the crashlog even if it doesn't seem useful to you.

Thanks.

How is this different from bug 184827?

[Rodrigo Kumpera]

This issue actually affects the Safari in the latest OSX.

We confirmed with our users that this is a regression introduced 
between `Safari 11.0.3 (13604.5.6)` and `Safari 11.1 (13605.1.33.1.2)`.

I haven't looked too hard. If you want to take a look this weekend feel free.

Cool. Looking into this now

[Saam Barati]

Seems like a real bug in NaturalLoops.

> Seems like a real bug in NaturalLoops.

I think this is the bug:

NaturalLoops's algorithm breaks down if a loop contains the same block more than once. This can happen in a case like this:

block:header
something
something
switch (case 1: header, case 2:header, etc)

I still don't know why exactly the algorithm breaks down, but it makes this loop produce wrong things inside the m_innerMostLoopIndices map:
```
        for (unsigned loopIndex = m_loops.size(); loopIndex--;) {
            NaturalLoop<Graph>& loop = m_loops[loopIndex];
        
            for (unsigned blockIndexInLoop = loop.size(); blockIndexInLoop--;) {
                typename Graph::Node block = loop[blockIndexInLoop];
            
                for (unsigned i = 0; i < std::tuple_size<InnerMostLoopIndices>::value; ++i) {
                    unsigned thisIndex = m_innerMostLoopIndices[block][i];
                    if (thisIndex == UINT_MAX || loop.size() < m_loops[thisIndex].size()) {
                        insertIntoBoundedVector(
                            m_innerMostLoopIndices[block], std::tuple_size<InnerMostLoopIndices>::value,
                            loopIndex, i);
                        break;
                    }
                }
            }
        }
```
I need to figure out why

[Saam Barati]

Seems mostly obvious why, actually. It'll do things for a block more than once now. That could make it compute things more than once in a way the algorithm isn't expecting for the same loop.

Just checked that it's fixed in Safari 12.0 (14606.1.30)

Also works fine in Safari 12 on iOS 12 beta 5 (dev)
