Aaron, I believe it's in your new code from bug 1542830 (part 4). Could you please have a look?

Component: Gecko Profiler → Telemetry
Flags: needinfo?(aklotz)
OS: Unspecified → Windows
Product: Core → External Software Affecting Firefox
Regressed by: 1542830
Assignee: nobody → aklotz
Status: NEW → ASSIGNED
Component: Telemetry → mozglue
Flags: needinfo?(aklotz)
Priority: P5 → P1
Product: External Software Affecting Firefox → Core

This assertion could fire if the profiler state changes between beginning and
ending a DLL load. That's less than ideal, so let's just get rid of it.
