Hi, I need some advice how to proceed with https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1099986 I've been unable to reproduce the crash on platti (testing and sid). In testing the autopkgtest fails since the upload of gcc-14 14.2.0-14: https://ci.debian.net/packages/c/cppcheck/testing/ppc64el/ For sid there is less data, but a matching date range: https://ci.debian.net/packages/c/cppcheck/unstable/ppc64el/I've also run the test suite with valgrind. There is a report about "conditional jump or move depends on uninitialized value(s)" that *could* be related to the crash, judging from the test output up to that point. The location is lib/vfvalue.h:163, but as far as I can see that member is always initialized from lib/vfvalue.h:317. For completeness, there are more reports of that location for the earlier tests, apparently without any bad consequences.Is there a way to tell autopkgtest to generate a core dump and a stack trace from it?
Not automagically, no, but we can provide you with a debug session inside a ppc64el autokpgtest container. Grabe me (terceiro) or Paul (elbrus) on the #debci IRC channel.
