Hi Fedorans, we are facing a very strange Python segfault in an OLPC build, based on F14, for XO-1.5 (I know, do you remember _that_ far ago?).
The state of the OS and disk is well known, but we cannot make it happen at will. So I got my hands on a coredump, installed the exact same OS (so exact matching disk state as the machine that segfaults, same rpms, etc), and went for http://fedoraproject.org/wiki/StackTraces#Obtaining_a_stack_trace_from_a_core_dump I've yum-installed the matching -debuginfo packages for python, glibc and glib (apparently the segfault is calling glib). Running gdb over the core, it complains: "the .dynamic section for "/usr/lib/python2.7 is not at the expected address", and suggests a yum install (of /usr/lib/debug/.build-id/<identifier>) that fails. Full error msg from gdb at http://fpaste.org/YqGv/ I can see that some packages have invalid debuginfo subpackages (http://fedoraproject.org/wiki/Packaging:Debuginfo#Useless_or_incomplete_debuginfo_packages_due_to_packaging_issues) , but given Python's importance to the Fedora stack, my bet is that Python's debuginfo is fine, and there's a subtle user error in the middle... To be clear -- we don't suspect Python or the Fedora stack. But something is rotten, and this segfault is the only clue we have. This problem is fairly important for the OLPC team at this time, help on this track appreciated. m -- martin.langh...@gmail.com mar...@laptop.org -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
