In several languages you can’t catch StackOverflowExceptions ([C# for example](https://stackoverflow.com/questions/1599219/c-sharp-catch-a-stack-overflow-exception))  
I believe this is because the stack is full so there is no space left to put the error handling frames.  
Other languages I believe keep some stack space reserved for this?

Can I rely on being able to catch StackOverflows in julia?  
For a particular part of my code I know stackoverflows are possible but that have a work around if the user defines the right methods.  
I would like to catch the stackoverflow if it does occur and give the user advise as to what methods they need to implement.

No. See [What to do about asynchronous exceptions · Issue #52291 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/52291).
