startup error on Windows11 24H2

[Niteip]

My program uses the mimalloc dynamic library, and when it starts on Windows 11 24H2, a popup error occurs stating, "The application was unable to start correctly (0xc0000142). Click OK to close the application." I have tested it and found that it works normally on Windows 11 23H2. Currently, I have switched the dynamic library to a static library, and users on Windows 11 24H2 are not encountering any startup errors.

Sorry for forgetting to mention that I am using version 2.1.7 of mimalloc

Yikes -- that's a bit scary. I recently updated the redirection dll; can you perhaps try with the latest dev-slice branch if you still see the same issue? (I am currently traveling and have no easy means to set up a test environment now).

Also, if it still fails, can you try with the environment variable MIMALLOC_VERBOSE=3 and see if there is any error output?

I have the same problem with the latest mimalloc-redirect.dll version

Ah great -- thanks, I'm looking into it. It is a bit strange to see an access violation inside ntdll though...
(I looked but couldn't find an obvious mistake on my side so I need to somehow set up a test environment with Win11 24H2, this may take a bit as I am traveling)

I updated mimalloc-redirect in the latest dev and dev-slice. This might fix the issue (but probably not). If you can try it that would be great.

[vitalyt79]

It didn't work for me, the same error.

[daanx]

Ok -- I need to get my hands on a 24H2 windows version then -- that would be earliest later next week though :-(

[vitalyt79]

ok, thanks a lot. BTW I'm using version 2.0.3.

Thank you for your work. I will test it tomorrow.

I updated mimalloc-redirect in the latest dev and dev-slice. This might fix the issue (but probably not). If you can try it that would be great.

I conducted two tests,
Test 1: Download dev, compile and obtain mimalloc-override.dll and mimalloc-redirect.dll, run, and get an error 0xc0000142
Test 2: Download dev-slice, perform the above steps, run it, and also report an error 0xc0000142
Then I tried compiling with MIMALLOC_VERBOSE=3, but I realized that when the error 0xc0000142 occurred, my program did not output any log files that it should have. What I mean is: Windows has a loader that does a bunch of checks on the program when it tries to run it, and only if it passes those checks does it create a process and then execute WinMain(). I guess that the error 0xc0000142 is not passed during the check stage, so there is no output log file, which means that MIMALLOC_VERBOSE=3 will not bring information.

I got my hands on Windows 24H2, version 10.0.26100.2314 (use winver to see this).

I could not reproduce the issue though.

I see patch 2314 came out on Nov 12 -- maybe this fixed the issue? Can you try this?

On my machine, winver shows 26100.1742

I tried the 2314 patch (downloaded from https://www.windowslatest.com/2024/11/12/windows-11-kb5046617-24h2-out-with-fixes-direct-download-msu/), after installing it and restarting my computer, winver showed 26100.2314.

Then, when I ran my program, the error 0xc0000142 still persisted.

I tried to create a new project with VS, a console application, and then introduced mimalloc (using the same dynamic libraries, mimalloc-override.dll and mimalloc-redirect.dll, following the same steps). When I ran it on Windows 11 24H2, everything worked fine, and the console printed "Hello World!".

Oh my goodness, now I'm completely at a loss. I don't know how to solve the issue with my program.

[vitalyt79]

For me the problem was solved after I added the inclusion of the <mimalloc-new-delete.h> to the file that contains the main function.
