0008-Fix-Globally-suppress-GCC-16-Warray-bounds-false-pos.patch Fix: Globally suppress GCC 16+ -Warray-bounds false positives (Closes: #1132057)


[ Description ]
Switching from local pragma fixes to global suppression for the
'-Warray-bounds' warning on GCC 16 and newer.

[ Technical Visualization ]
The following diagram illustrates why the compiler's static analysis
fails to correctly map the object boundaries in 7-Zip's architecture:

1. ALLOCATION:
An object (e.g., CHandler) is allocated with a fixed size (N bytes).

2. MULTIPLE INHERITANCE / COM CASTING:
The object inherits from multiple interfaces. When accessed via a
specific interface pointer, the "vtable" and "member offsets"
shift relative to the base pointer.

3. OPTIMIZER MISINTERPRETATION:
+-------------------------------------------------------+
| [VTable A] | [VTable B] | [_m_RefCount] | [Data...] |
+-------------------------------------------------------+
^ ^ ^
| | |
| | +-- GCC Flags: "Access here is out of bounds!"
| | (Based on an incorrect inferred size)
| +-- Interface B Pointer
+-- Interface A Pointer / Original Object

[ Reason for Global Suppression ]
While local pragmas (push/pop) are generally preferred, the recurring
nature of this error across various modules (HandlerCont.cpp,
RarHandler.cpp, FilterCoder.h, etc.) indicates a systemic conflict
between 7-Zip's COM-like architecture and modern GCC's devirtualization
logic.

Globally ignoring this specific warning for GCC 16+ is the most
maintainable solution to ensure build stability without refactoring
the entire interface system.		 YOKOTA Hiroshi <yokota.hgml@gmail.com> yes 2026-03-29
