Description

We are currently using mimalloc with dynamic library override on Windows Server 2008 R2. Our server application ran normally with mimalloc versions 3.3.2 through 3.4.5. However, after upgrading to version 3.5.0, the program hangs at startup, with only the ntdll thread remaining active.

Research direction

Reproduce the startup hang using mimalloc 3.5.0 with dynamic library override on Windows Server 2008 R2, then compare the behavior with versions 3.3.2–3.4.5. The issue names no source files, tests, or entry points; done means the application starts normally with 3.5.0 and the regression is identified and verified.
