EVE Online random crashes
Hey there, when I'm playing EVE online I get random crashes while I'm playing. These always occur while I'm out in space, never when I'm updating my trade orders. Using ati drivers: 10.11 Wine: 1.3.20 This is shown in console when the game crashes... Code: An exception has occurred.

...uot; and branch. The logic to generate the branch target should largely be the same as logic to generate the landing pad block. 2. low exception volume -- keep the invoke, but put a deoptimization trap in the landing pad block. We did some rough benchmarking, and using such implicit exceptions (i.e. not explicitly checking the pending exception word) reduces non-throwing call overhead by 20-25%. I don't have any numbers on how it affects the performance of exceptional control flow though. -- Sanjoy

[LLVMdev] Question about implementing exceptions, especially to the VMKit team
Hi all, I'm working on implementing exceptions in Pyston, and I was hoping to get some guidance from the list. I think I've learned enough about C++-style DWARF exceptions to convince myself I have a workable approach, but then I found this VMKit paper (2010) which says The exception manager: To manage exceptions, J3 reserves a > word...

I am trying to install some application using gem, but I keep on getting the error. I tried with ''gem clean'' and ''gem update''. The latter gives the following error (the same error is replicable when I try any ruby applications): # gem update --debug Exception `Errno::ENOENT'' at /usr/lib/ruby/site_ruby/1.8/rubygems/config_file.rb:51 - No such file or

Disabling Exception in LLVM
Hi Chris, Thanks for answering, Can u clarify on this comment mentioned in https://github.com/Z3Prover/z3/issues/861 . cplusplus no exception support · Issue #861 · Z3Prover/z3 · GitHub - LLVM's *source code* does not use exceptions for performance reasons and so is compiled by default with -fno-exceptions. When using LLVM's libraries via it's C++ interface it is important to match how LLVM was built (i.e. do not mix code built with and without exception support). - The Clang compiler which is built on top...

[LLVMdev] C++ Exception Handling Problem
Hello, I'm in the process of creating a JIT and I've run into a problem with exception handling. The situation I'm in is that my program will JIT functions, which will call native C++ functions (part of the run-time support). These native functions can throw exceptions. However, I don't actually want to handle these exceptions in the JITted functions. There are already try/catch blocks in place in the C++ function that calls the JITted functions. The problem I run into is that when exceptions are thrown, they aren't caught anywhere. My program crashes w...

Disabling Exception in LLVM
LLVM does not allow the use of exceptions in our code. We do not allow throwing or catching them. That does not mean you cannot compile the code with exceptions enabled, it just means we don't use them. Clang is a full C++ compiler. Even though LLVM & Clang do not use exceptions in their implementation, Clang does support compilin...

controller exceptions
Since Merb has the lovely property of rendering the output of an action, using ruby-level exceptions to render error pages in Merb could be a cute way to approach error handling. Suppose one has an action for editing a product which you would like to restrict to administrators: def edit raise AdminAccessReqired unless session[:user] and session[:user].admin? @product = Product.find(par...

That's a fairly uncommon property to hold - most code calls other external functions.

That's a neat model. What happens if two (or more) exceptions are thrown while you're cleaning up another? For instance, if A's destructor also throws an exception? A's exception was not thrown while processing B's exception (but while cleaning up *before* processing it), so it's not a nested exception, but an "aside" exception....
