Try job failure for 10836190-1 (retry) on linux_rel for step "update".
It's a second try, previously, step "browser_tests" failed.
http://build.chromium.org/p/tryserver.chromium/buildstatus?builder=linux_rel&...

Step "update" is always a major failure.
Look at the try server FAQ for more details.

DCHECK((uint32_t) addr_count > count ||
Shouldn't it be static_cast<uint32_t>(addr_count)?
