[PATCH 0/1] MR10471: unwind: fix some invalid `reinterpret_cast`s
by Safocl Stollmannovic (＠safocl88) March 27, 2026

March 27, 2026

Performing type `reinterpret-cast`s between pointers to types that are not _pointers-interconvertible_ and then using the results is incorrect usage. Only the “array of N unsigned char” or of type “array of N std::byte” types can used as storage (in general case). To convert a pointer to a structure object containing a byte array into a pointer to an object explicitly created in that storage, std::launder must be called on that "newly typed" pointer. Accessing an explicitly created object in such a byte store through a pointer to an object of the structure type that contains the given byte array requires calling std::launder. ```cpp struct S { unsigned char data[_LIBUNWIND_CURSOR_SIZE * sizeof(uint64_t)]; } s; struct S2 { int i; }; new(s.data) S2(42); auto s2_ptr1 = reinterpret_cast<S2*>(s.data); auto s2_ptr2 = reinterpret_cast<S2*>(s); // this pointer is not changed ([expr.static.cast#12]) and points to s (struct S) auto s2_ptr3 = std::launder(reinterpret_cast<S2*>(s)); int i1 = s2_ptr1->i; // OK int i3 = s2_ptr3->i; // OK (?) int i2 = s2_ptr2->i; // this is undefined behavior ``` Also a pointer to object of type uint16\[2\] cannot be reinterpreted as uint32 -- this is undefined behavior (https://godbolt.org/z/vY1zKEvo6) https://eel.is/c++draft/intro.object#3 https://eel.is/c++draft/basic.compound#5 https://eel.is/c++draft/basic.compound#6 https://eel.is/c++draft/basic.lval#11 https://eel.is/c++draft/expr.static.cast#12 https://eel.is/c++draft/expr.reinterpret.cast#7 https://en.cppreference.com/w/cpp/utility/launder.html https://en.cppreference.com/w/cpp/language/reinterpret_cast.html -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10471

[PATCH v3 0/7] MR10009: mf/topology_loader: Fix some topology loader test failures.
by Conor McCarthy (＠cmccarthy) March 27, 2026

March 27, 2026

A followup MR will move converter connection behaviour closer to native, and maybe revise decoder connection a bit. -- v3: mf/topology_loader: Load the down connection method in topology_branch_connect(). mf/topology_loader: Enumerate branch up types if the node has no current type. mf/topology: Actually set types for transforms in IsMediaTypeSupported(). mf/topology_loader: Load the branch up connection method only for source nodes. mf/topology_loader: Delete unused struct connect_context. mf/topology_loader: Do not create a new branch list containing downstream nodes. mf: Trace additional topology details. https://gitlab.winehq.org/wine/wine/-/merge_requests/10009

[PATCH v8 0/1] MR10461: Draft: vbscript: Implement IDispatch::GetTypeInfo for class instances.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Implement GetTypeInfo on vbdisp_t (VBScript class instances) by returning an ITypeInfo that reports the class name via GetDocumentation(MEMBERID_NIL) and exposes public methods and properties via GetFuncDesc, GetVarDesc, GetNames, GetIDsOfNames, and GetTypeAttr. This makes TypeName() return the actual class name (e.g. "MyClass") instead of falling back to "Object". This is partially based on previous work by @jsm174 at https://github.com/jsm174/libwinevbs/blob/fbc4d2a17a2da8196d50805f7ae289406… -- v8: vbscript: Implement IDispatch::GetTypeInfo for class instances. https://gitlab.winehq.org/wine/wine/-/merge_requests/10461

[PATCH v5 0/1] MR10464: vbscript: Return "Name redefined" error for duplicate declarations.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

When a name is defined twice (Const/Const, Dim/Const, Const/Dim, Dim/Dim, Sub vs Const/Dim, Class vs Const/Dim/Function), Windows returns VBScript error 1041 ("Name redefined"). Wine was returning E_FAIL. Store the identifier location in const_decl_t and dim_decl_t so errors point to the duplicate name, not the keyword. -- v5: vbscript: Return "Name redefined" error for duplicate declarations. https://gitlab.winehq.org/wine/wine/-/merge_requests/10464

[PATCH v7 0/1] MR10405: vbscript: Return proper error for undefined variables with Option Explicit.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

When Option Explicit is set and an undefined variable is used, return VBS error 500 (Variable is undefined) with the variable name in the description, matching Windows behavior. Previously Wine returned E_FAIL with no description. -- v7: vbscript: Return proper error for undefined variables with Option Explicit. https://gitlab.winehq.org/wine/wine/-/merge_requests/10405

[PATCH v46 0/2] MR10291: Fix GetModuleFileName string termination
by Trent Waddington (＠trent.waddington) March 27, 2026

March 27, 2026

After Windows XP the string termination behavior of GetModuleFileName was changed to always terminate the path returned, even if the buffer is insufficient to contain the null terminator. -- v46: kernel32: Fix string termination of GetModuleFileName https://gitlab.winehq.org/wine/wine/-/merge_requests/10291
