App crashes on German Windows at ntdll.dll
« on: 23 Feb '24 - 21:17 »
My app (432Hz Converter) works perfectly find for thousands of users, on Windows, Linux and MacOS.

EXCEPT this one German guy, he gets this crash on startup:

Application-ID relative to failed package:

ntdll.dll generally has to do with a memory leak in unmanaged code. The only managed code I have is BASS audio. This looks like a bug in BASS. This is the only user affected so far. He tried running without the 'müll' folder and that changed nothing.

(btw I still have to send you some money for the usage license. I'm absolutely not in a position to do so now, but when I do, I'll send some)

0xc0000409 means STATUS_STACK_BUFFER_OVERRUN. In other words, something in your program is writing past the current stack frame, corrupting data ...

My .NET program doesn't start; and you can't achieve such error with managed code.

If you haven't already done so, please first get the user to try this latest BASS build, and if the problem still happens then get a dump file from it (while using this latest BASS build) for more info. Windows may already be generating dump files in the "%LOCALAPPDATA%\CrashDumps" folder, but if not, this "localdumps-full" registry entry can be used to enable that.

The dump file can be uploaded here:
