Bug 141039 – Web Inspector: ASSERT in InspectorTimelineAgent::internalStop

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector

[Eric Carlson]

Stopwatch ASSERT when using inspector. r178433 fixed a Stopwatch::stop ASSERT in InspectorDebuggerAgent, but InspectorTimelineAgent also has a Stopwatch so it apparently needs a similar fix.


ASSERTION FAILED: !isnan(m_lastStartTime)
