From 968c4a47e21f0ee9943495a4ca5b2558a42a78c4 Mon Sep 17 00:00:00 2001 From: Geoff Franks Date: Tue, 26 May 2026 11:21:01 -0400 Subject: [PATCH 1/2] Fix Windows compatibility for fake app SIGABRT simulation Replaces syscall.Kill usage with cross-platform panic approach to simulate SIGABRT behavior. On Windows, syscall.Kill is not available, so using panic provides consistent abnormal termination behavior across platforms. Changes: - Remove syscall import and usage from fake apps - Use panic() for exit code 134 (SIGABRT simulation) - Update unit tests to expect panic exit code (2) instead of platform-specific SIGABRT codes - Maintains cross-platform compatibility for Windows builds The panic approach provides equivalent abnormal termination behavior as SIGABRT while working on all supported platforms.
