gdb/gdb-btrobust.patch
Michael Matz c7081b119c - Rebase to gdb version 7.10.1 as of version in Fedora 23:
* reverse debugging on aarch64
  * new commands or subcommands:
    - info os cpu, set/show serial parity, info dll
    - maint print symbol-cache/symbol-cache-statistics,
      maint flush-symbol-cache
    - record btrace bts, record bts
    - compile print
    - show/set mpx bound
    - tui enable/disable
    - record btrace pt, record pt
    - maint info btrace,
      maint btrace packet-history/clear-packet-history/clear
  * s390 support for vector ABI
  * "set sysroot" improvements related to remote targets
  * better support for debugging containerized programs
    (without "set sysroot")
  * HISTSIZE environment variable is replaced by GDBHISTSIZE
  * python scripting:
    - it's possible to write frame unwinders
    - several new methods in Objfile, Type and Value classes
    - gdb can auto-load scripts contained in special sections
      named '.debug_gdb_scripts'.
  * extensions for the MI interface, new remote packet types
- Removed obsolete patches:
    0001-S390-Add-target-descriptions-for-vector-register-set.patch
    0001-S390-Fix-compiler-invocation-with-compile-command.patch
    0001-S390-Support-new-vector-register-sections.patch
    0002-S390-Add-vector-register-support-to-gdb.patch
    0003-S390-Add-vector-register-support-to-gdbserver.patch

This should fix the error with glib. An error message will still be
printed, but a default backtrace will occur in this case.
