64-bit chromium should be able to support loading 32-bit plugins

Reported by, Jun 24 2010

Issue description

Chrome Version       :

Chromium	5.0.375.70 (Developer Build 0)
WebKit	533.4
User Agent	Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.70 Safari/533.4
Command Line	 /usr/lib64/chromium-browser/chrome

Sorry if this is a dup.

Because chrome/chromium runs plugins in a separate process and uses IPC to handle communication between the actual browser and the plugin's process, it should be able to support loading both 32-bit and 64-bit plugins in the 64-bit build. Obviously a 64-bit process is capable of launching a 32-bit or a 64-bit process.

This is essentially what things like "nspluginwrapper" do already. But unlike firefox (well until 3.6.4, which now runs things in a separate process), chrome/chromium is already designed to run plugins in a separate process.

Obviously it is a over-simplification, but the way I envision such a feature working (at least in the *nix family) is having a separate 32-bit binary for handling 32-bit plugins. After the usual fork is executed, simply parse the ELF file header and determine if it is 64-bit or 32-bit, then optionally execve the 32-bit plugin handling binary.

We're going to be doing this for the Mac; hopefully most of the code will be shareable.

What does Status:Available + Mstone-X mean? 
Is the problem solved but not merged into a release?
See the bug status descriptions at:
Available means it's acknowledged as a bug but not currently assigned to anyone.
Found the answer: 
Would be great if was someone could fix it for Linux. My use case is that I need to run the java plugin in 32 bits because Webex crashes otherwise.

Chrome for Linux no longer supports NPAPI plugins.
