CRASH "library initializer failed" on Windows SDK 10.0.26100.0

[sklaw]

Describe the bug On Windows, when compiled with Windows SDK 10.0.26100.0, clients would crash with "library initializer failed". This occurred on multiple clients, including the "empty" sample client. This does not occur when compiled with older SDKs.

To Reproduce Steps to reproduce the behavior:

1. Install Visual Studio 2022 with Windows SDK 10.0.26100.0
2. Create a CMake project.
3. Set the following values in CMakePresets.json:

   {
   "configurePresets": [
       {
           ...
           "generator": "Visual Studio 17 2022",
           "cacheVariables": {
                "DynamoRIO_DIR": <path to dynamorio installation/release's cmake folder>,
                "CMAKE_GENERATOR_PLATFORM": "version=10.0.26100.0",
                ...
           },
           ...

4. Write a simple client for the project.
5. Build the project.
6. Test the output DLL with drrun.exe

Please also answer these questions:

• What happens when you run without any client?
  • No error.
• What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)?
  • Crashed with "library initializer failed"

Screenshots or Pasted Text Command prompt output of injecting a simple client into tasklist:

Versions

• What version of DynamoRIO are you using?
  • DynamoRIO version 10.93.19965, Windows release
• Does the latest build from https://github.com/DynamoRIO/dynamorio/releases solve the problem?
  • No
  • What operating system version are you running on? ("Windows 10" is not sufficient: give the release number.)
  • Windows 11 Home, 23H2
  • Is your application 32-bit or 64-bit?
  • Tested on both.

Thank you for the detailed report. Adding back the newlines to the log from above:

SYSLOG_ERROR: Application C:\Windows\system32\tasklist.exe (42524). Unable to load client library: myclient.dll: library initializer failed.. 

It looks like it's the myclient itself, and not some system library, that crashed: privload_call_entry: myclient.dll init routine 0x00007ff5b4fa1460 crashed!. Yet the crash PC is in dynamorio.dll: ASYNCH intercepted exception in thread 15100 at pc 0x00000000150ffec7. A redirected library import?

Would it be possible for you to run under a debugger and get the callstack of the Access Violation at 0x00000000150ffec7?

[sklaw]

You're welcome!

I found out that the second to last insturction before crashing is the syscall in NtRaiseException.
