http://bugs.winehq.org/show_bug.cgi?id=58584 --- Comment #7 from Danny Waser <waser(a)waser.tech> --- The log confirms the crash is an `EXCEPTION_ACCESS_VIOLATION` (c0000005) occurring at address `0x...C20EFBD`, which is inside the native `CONCRT140.dll` module loaded at `0x...C1F0000`. Most importantly, just before the crash, the log shows a call to a semi-stubbed function: ``` 0134:fixme:heap:GetNumaHighestNodeNumber semi-stub: 000000000011FC20 ``` This strongly suggests that the crash is caused by the MSVC concurrency runtime receiving incomplete NUMA information from Wine, leading to an access violation when it attempts to initialize its thread pools. This reinforces the theory that the root cause is in Wine's implementation of modern CPU/memory features required by the concurrency runtime. The `GetNumaHighestNodeNumber` function is expected to return the highest NUMA node number available on the system, which is crucial for applications that rely on NUMA-aware memory allocation and thread management. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
