Created attachment 8927342 [details] log.tar.xz Hit MOZ_CRASH() at z:/build/build/src/xpcom/build/LateWriteChecks.cpp:116
Created attachment 8927810 [details] [diff] [review] Patch I suppose the failure is due to the fact that the instrumented build is writing the coverage counters on exit. I'm not sure why there's no crash on Linux.
Pushed by firstname.lastname@example.org: https://hg.mozilla.org/integration/mozilla-inbound/rev/15fa308daad3 Don't crash when there are late writes in the Windows coverage build. r=froydnj
