- Issues
- Try optimize without allocation
- Regex: Compiled and source generator give wrong results for `(?>.*\b)` (regression in .NET 10)
- Linux: with #134717 in only one of mscordbi and coreclr, a short debugger event is still read with stale bytes (debuggee SIGSEGV, or a freed pointer freed again)
- Unix: mscordbi writes `Debugger::m_RSRequestedSync` before every debug event, but no Unix runtime reads it (about a third of the messages in a launch-and-stop session)
- `TarFile.ExtractToDirectory` may be Significantly Slower than Windows `tar.exe`
- [ci-scan] Test failure: Interop/COM/NativeClients/Dispatch/Dispatch.cmd exits 0xC0000409
- Linux/macOS: the debugging services reap a launched debuggee with `waitpid` and drop its exit status, so debuggers report "exited with code 0" for a crash (re-raising #43731)
- Debugger Hot Reload with a profiler loaded: `CanSetEnCBits` refuses it, `DOTNET_MODIFIABLE_ASSEMBLIES=debug` allows it. Is that the supported route?
- cDAC: a cyclic Frame chain makes IStackWalk.CreateStackWalk loop forever
- JIT: Compare 128 To 127
