Línea de trabajo

The issue points to failures in the CMake quickstart tests, specifically in the fedora-latest-cmake-quickstart-production build. Start by examining the build logs linked in the issue to see the exact error messages and the quickstart runner script at /workspace/cmake/quickstart-runner.cmake. Look at the failing quickstarts like networksecurity_quickstart and those with memory corruption errors to understand the common dependencies or library interactions. Determine if the issue is in a core library, a dependency ABI mismatch, or the test configuration itself by reproducing the build environment and running the quickstarts locally.

Descripción

cpp: flake

While triaging GCB failures, I found a recurring failure in fedora-latest-cmake-quickstart-production.

The build officially fails because networksecurity_quickstart repeatedly times out after 300 seconds:

CMake Error at /workspace/cmake/quickstart-runner.cmake:90 (message):
  Non-zero exit status (Process terminated due to timeout) running
  /workspace/cmake-out/google/cloud/networksecurity/networksecurity_quickstart

However, the raw logs show a much deeper systemic memory corruption issue. Several other quickstarts are crashing violently but showing as "Passed" because of the --repeat until-pass:3 CTest flag.

Examples from the logs:

  • backupdr_quickstart & alloydb_quickstart: double free or corruption (fasttop)
  • video_quickstart: corrupted double-linked list
  • servicedirectory_quickstart: malloc_consolidate(): unaligned fastbin chunk detected
  • gkebackup_quickstart & vpcaccess_quickstart: Segmentation fault

This looks like a regression in a core library or a dependency ABI mismatch causing heap corruption.
