“I work on Chrome, on Windows” ... chrome_child.dll (stack base) KernelBase.dll!VirtualAlloc ntoskrnl.exe!MiCommitVadCfgBits ntoskrnl.exe!MiPopulateCfgBitMap ntoskrnl.exe!ExAcquirePushLockExclusiveEx ntoskrnl.exe!KeWaitForSingleObject (stack leaf) So don’t use a proprietary kernel that performs poorly?

I'm confused about your suggestion. I work on the Chrome web browser on the Windows platform. If we want to allocate memory we, ultimately, need to call VirtualAlloc. I could work on Chrome for Linux, but then this bug on Windows might never get found or fixed. I am satisfied with my choices, despite the occasional glitches.

  Thanks for the fascinating and informative detective story, Bruce. (And the bugfix, of course)

  They failed to distinguish between "I use the Chrome browser on Windows to get work done" and "I work at Google, making Chrome for Windows". Human languages, what are you going to do?
  - brucedawson 8y ago
    Good point. How's this: I modify the source code of the Chrome browser in order to make the final PE files that are compiled from the aforementioned source code work more efficiently.

      Or how about "I work at Google, making Chrome for Windows".

    For what it's worth I also read it as "I use the Chrome browser on Windows to get work done" and only slowly figured out the correct interpretation as the debugging adventure got crazier and crazier.

    Fixed in the post, finally. Thanks.

Does Linux has ETW or something of similar level?
- brucedawson 8y ago
  The Linux "perf" tool is amazingly powerful, but it's user interface is... not ideal. That said, WPA (the UI for ETW) is complex for new users, but mostly only necessarily so.

    perf has a nice UI nowadays, hotspot : https://github.com/KDAB/hotspot https://github.com/KDAB/hotspot

  Probably "perf" would work here.
