As written, the VerifyStackReadWithMultipleThreads unit test makes assumptions about the layout of thread_function's stack frame. As a result, the test will fail when compiled with some compilers, or built with certain optimization levels. As an extension to C++, the GNU compilers allow you to request that a variable be placed in a specific register. Using this, we can have thread_function put the thread id in place where the test can find it reliably. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@558 4c0a9323-5329-0410-9bdc-e9ce6186880e
