[PATCH v6 0/1] MR10317: vbscript: Allow Not operator as operand of comparison expressions.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

vbscript: Allow Not operator as operand of comparison expressions. The Not operator was only reachable from the NotExpression grammar rule, which sat above EqualityExpression in the precedence chain. This meant expressions like "a <> Not b" caused a syntax error because the right-hand side of a comparison could not contain Not. Fold Not directly into EqualityExpression as a unary prefix and use bison precedence declarations to resolve the resulting ambiguity: %right tNOT at lower precedence than %left comparison operators ensures "Not 1 = 2" parses as "Not(1 = 2)" while "a <> Not b = c" correctly lets Not capture the comparison on its right.

Re: [PATCH v24 0/2] MR10295: Fix ImageGetDigestStream
by eric pouech (＠epo) March 27, 2026

March 27, 2026

thanks for updating this the good news is that this passes the tests, with some interesting coverage the bad news is that the MR fails on the first real .exe I tested against (only the flags CERT_PE_IMAGE_DIGEST_RESOURCES |CERT_PE_IMAGE_DIGEST_ALL_IMPORT_INFO generate correct information) (for the other flags, the tests show different values for nt header and section blobs; to start with) I tested then only this flag combination on a greater deal of images, and some fail; it seems however they all fail the same way: they miss to report an entire section; didn't investigate further the cause; but this doesn't look to complicated what I suggest for the next step is to concentrate on this set of flags (it seems you're not too far way for getting it right); and put a FIXME at the start of function in case the flags don't match that set; then in subsequent commits (could be even a different MR) start implementing the extra flag combination (test used mainly prints size + md5 of each blob reported in callback and compare text output on native & biultin) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10295#note_134105

[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
