Title:
  gdb crashed with SIGSEGV in response to strace command with no
  arguments

Status in GNU Debugger:
  Fix Released
Status in “gdb” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: gdb

  gdb (package version 7.2-1ubuntu3 on Maverick amd64) segfaults when
  given the strace command with no arguments:

  (gdb) strace
  Segmentation fault (core dumped)

  strace with arguments does not cause a crash, and appears to work
  correctly. This bug also occurs when gdb is debugging a running
  program and the strace commad is issued without arguments (i.e., it
  does not only happen in the trivial case shown above).

  I am able to reproduce this bug on Maverick i386 (same gdb package
  version as above) and Natty i386 (gdb package version  package version
  7.2-1ubuntu6) as well.
