--- Comment From emach...@br.ibm.com 2014-10-20 13:08 EDT--- Tested and verified as fixed with gdb 7.8-1ubuntu4. Thanks. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gdb in Ubuntu. https://bugs.launchpad.net/bugs/1376281 Title: gdb: Can't read symbols from system-supplied DSO at 0x3fffb7fa: File truncated Status in “gdb” package in Ubuntu: Fix Released Bug description: ---Problem Description--- GDB produces an odd message about a failure to read symbols from the system DSO when running executables on LE Ubuntu 14.10 with 3.16 kernel. This is a regression from LE Ubuntu 14.04, where the message is not produced. Bad case: $ uname -r 3.16.0-6-generic $ gdb /bin/ls GNU gdb (Ubuntu 7.7.91.20140723-0ubuntu1) 7.7.91.20140723-cvs ...

[Inferior 1 (process 1573) exited normally] (gdb) Note the Can't read symbols... message. Good case (LE Ubuntu 14.04): $ uname -r 3.13.0-32-generic $ gdb /bin/ls GNU gdb (Ubuntu 7.7-0ubuntu3.2) 7.7 ... (gdb) run Starting program: /bin/ls ... [Inferior 1 (process 91140) exited normally] (gdb) I haven't tried on the 3.15 kernel, so I don't know if the problem is sensitve to the 3.16 kernel being ELFv2. ---uname output--- Linux tul115p1 3.16.0-6-generic #11-Ubuntu SMP Mon Jul 28 02:00:45 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux Machine Type = 8286-42A ---Steps to Reproduce--- See description; occurs when running any application under gdb. The failing output above is with the 3.16 kernel supplied by Ubuntu, so the problem happens both with locally-built and Canonical/Ubuntu-supplied kernels on 14.10. This issue was recently fixed on upstream binutils-gdb: https://sourceware.org/ml/gdb-patches/2014-09/msg00594.html The attached patch against gdb 7.8-0ubuntu1 for Ubuntu 14.10 fixes the issue.
