Hey thanks to Johann, I got wine to install correctly on my amd64. Then I installed winetools. When I run the newest build, version 2.1.1., and try to install windows software, i get this output: bash-2.05b$ winetools found gettext in /usr/bin which: no dillo in

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. It has been logged in the log server as exception #8 An exception has occurred. It has been

Hi Kevin, To elaborate on Philip's point, depending on the state Pyston's runtime already is in, you may have the choice of using a hybrid of a "pending exception" word in your runtime thread structure, and an implicit alternate ("exceptional") return address for calls into functions that may throw. This lets you elide the check on the pending exception word after calls by turning them into invokes that unwind into a landingpad containing a generic exception handler. This generic exception handler then checks the type of the pend...

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 for the pending exception in the local storage of

Hello All I'm settup my asterisk as belows: sangoma card, connected with E1, CAS Signalling. I have two problem. 1.

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

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

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

Bill, I believe the empty-exception-specification example is a red- herring, but that if you can construct an example where you think a landing-pad requires multiple filter lists then I think we can then have a productive conversation about it. I believe we can only get multiple filter lists in a landing-pad if we attempt to merge exception-regions, and since filters are only an

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 compiling C++ code that uses exceptions. Does this answer your

...def action @id = params[:id] render # views/exceptions/unknown_product.rhtml end end If passed a bad id, the server will respond with 404 and a page that is specific to missing a product. The advantages of this scheme are - Simplifies controller action definitions by placing exceptional logic elsewhere - Eases the conformity to HTTP by returning proper error codes - Could allow for before and after filters around a restricted type of exceptions (eg, for logging purposes) - Further modularizes testing code: one needs only to check that an action raise a particular exception Though...

Is LLVM expressive enough to represent asynchronous exceptions? --------------------------------------------------------------- Summary: Need new LLVM instructions or extending of all instructions. C++ exceptions are synchronous: the compiler knows when/where they are being raised. Asynchronous exceptions can be raised at any time. For example, an integer divide-by-zero may raise an

ZCEH makes a complicated performance tradeoff wherein the exceptional case is penalized in order to optimize the common case. Since C++ code has many implicit try/finally blocks (each stack-based object with a destructor), this is a clear win.
