gdb message "Got object file from memory but can't read symbols: File truncated."

Status changed to 'Confirmed' because the bug affects multiple users.

This is likely the cause of the upstream Python test suite failures.

This is fixed upstream:
https://sourceware.org/ml/binutils/2014-09/msg00140.html

This bug was fixed in the package gdb - 7.8.1-1ubuntu1

---------------
gdb (7.8.1-1ubuntu1) vivid; urgency=medium

  * Merge with Debian; remaining changes:
    - Build from the upstream sources.
    - Build the gdb-doc package.
    - Include the man pages in the gdb package.
    - Build-depend on gcj-jdk.
    - Drop build dependency on python-dev.
    - Additional patches branch-updates, gdb-strings, ptrace-error-verbosity,
      ppc64el-gdbserver, ppc64el-attach-jvm.
    - Don't build a gdb-python2 package.
    - Configure with babeltrace on ppc64 and ppc64el.
    - gdb: Add a replaces to gdb-doc, which used to ship the manual pages.
    - Again, stop building the gdb-minimal package, not used anymore on any
      image.
    - Add build dependencies for the gdb-doc package.
    - Make gdb Multi-Arch: allowed again.
