Package: libqbscore1.12 Version: 1.12.1 Severity: normal Tags: patch upstream
Enabling --log-level debug (or using --more-verbose) (in the build of dewalls) causes the build to fail with a segfault. This has been discussed upstream and a fix for the null pointer dereference produced. Please apply the attached patch to the package until the next release when you should be able to drop this patch. Details are in this thread: https://lists.qt-project.org/pipermail/qbs/2018-December/002290.html (some of it was not copied to the list) You can reproduce/test it as follows: Install the debug version of libqbscore1.12. Get the dewalls package, unpack it, cd into it and run dpkg-buildpackage so the 'deb' profile is set up. then run qbs build --settings-dir /tmp --log-level debug --command-echo-mode command-line --no-install profile:deb modules.qbs.installRoot:/home/wookey/packages/cavewhere/dewalls/debian/dewalls-1.0.0/debian/tmp project.libDir:lib/x86_64-linux-gnu config:qbs-build You'll need to adjust the installRoot path. it fails with: qbs.moduleloader: Resolving Probe at "/usr/share/qbs/modules/bundle/BundleModule.qbs:46:5" qbs.moduleloader: Probe disabled; skipping qbs.moduleloader: reset instance scope of module "Qt.core" in property "cxxFlags" of module ("cpp") Thread 3 "QThread" received signal SIGSEGV, Segmentation fault.

Description: Fix for segfault with --log-level debug A segfault can occur when the debug logging level is enabled if the 'sourceCode' value is null.
