--- Comment #4 from Fujii Hironori <Hironori.Fujii at sony.com> ---
I applied a patch to show returncode to trunk at 234190.
Here are the patch and the log.
https://gist.github.com/fujii/92f167fe59c231247d39ded503320bd8

There are two values of returncode, -1073741819 and -4.

> 15:48:38.313 3196 This test marked as a crash because of failure to poll the server process. returncode=-1073741819
> 15:48:47.289 24964 This test marked as a crash because of failure to poll the server process. returncode=-1073741819
> 15:50:09.235 9780 This test marked as a crash because of failure to poll the server process. returncode=-4
> 15:50:09.471 9780 This test marked as a crash because of failure to poll the server process. returncode=-4

-4 is the reurncode of consecutive DumpRenderTree crash.

returncode should be the valud of GetExitCodeProcess.
It's weird it is a negative value.
Looking though Python-2.7.15 source code, I can't find the code it makes negative.
