Malcolm has been continuing work on the static analyzer support (-fanalyzer) for the GNU Compiler Collection with yet more enhancements in this area. For one, GCC 14 gains a new "-Wanalyzer-infinite-loop" option to try to detect simple cases of infinite loops occurring.
Building off the analyzer's out-of-bounds warnings from GCC 13, the GCC 14 compiler is bringing improved visualizations for buffer overflows. Malcolm has worked out some nice text-based diagrams for better showing buffer overflow warnings so developers can better grasp the issue. Here are two example shared by David Malcolm of the improved ASCII art for visualizing a buffer overflow:
The GCC 14 analyzer also has improved support for analyzing C string operations, new taint-based warnings are now enabled by -fanalyzer, and more.
The stable GCC 14.1 compiler release is expected in the coming weeks. More details on these GCC 14 static analyzer improvements via the Red Hat Developers blog .
