Description

When hitting a DCHECK/CHECK the daemons do not write minidumps. This is caused by glog's own stack unwinding mechanism, which catches SIGABRT and removes all other handlers before aborting.

This issue mostly affects debug builds, where DCHECK is enabled, as we only use CHECK at a handful of places (outside of tests).
