Title:
  gcore does not execute, uses /bin/sh but requires bash

Status in gdb package in Ubuntu:
  Confirmed

Bug description:
  gcore fails to execute on bionic

  $ gcore
  /usr/bin/gcore: 28: /usr/bin/gcore: Syntax error: "(" unexpected

  Line 28 is:
   28 dump_all_cmds=()                                                                

  This appears to be bash syntax for arrays (as reinforced further down)
  which is not compatible with the /bin/sh shebang using dash.

  Upstream has a recent commit to move this from /bin/sh to bash (along also making other changes to fix problems with quoting within the same commit):
  https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=e1e6f073a9f5d7c3183cb8096fb24a42c28ba36b

  As a minimum fix we should probably change it from /bin/sh to
  /bin/bash
