    I have a problem with history-search-backward & history-search-forward
    behaving differently on two machines.

    The first machine is running Redhat Gnu/Linux version 7.3 with bash
    version 2.05a

    Here is the autogenerated info from bashbug:

    Configuration Information [Automatically generated, do not change]:
    Machine: i686
    OS: linux-gnu
    Compiler: gcc
    Compilation CFLAGS: -DPROGRAM='bash' -DCONF_HOSTTYPE='i686' -DCONF_OSTYPE='linux-gnu' -DCON\
    F_MACHTYPE='i686-pc-linux-gnu' -DCONF_VENDOR='pc' -DSHELL -DHAVE_CONFIG_H -D_GNU_SOURCE -I\
    . -I. -I./include -I./lib -O2 -march=i386 -mcpu=i686
    uname output: Linux plato.csl.sri.com 2.4.20-20.7smp #1 SMP Mon Aug 18 14:46:14 EDT 2003 i68\
    6 unknown
    Machine Type: i686-pc-linux-gnu

    Bash Version: 2.05a
    Patch Level: 0
    Release Status: release

    The second machine is running Redhat Fedora Core 1 with bash version
    2.05b.

    Here is the autogenerated info from bashbug:

    Configuration Information [Automatically generated, do not change]:
    Machine: i386
    OS: linux-gnu
    Compiler: i386-redhat-linux-gcc
    Compilation CFLAGS: -DPROGRAM='bash' -DCONF_HOSTTYPE='i386' -DCONF_OSTYPE='linux-gnu' -DCONF_MACHTYPE='i386-redhat-linux-gnu' -DCONF_VENDOR='redhat' -DSHELL -DHAVE_CONFIG_H -I. -I. -I./include -I./lib -D_FILE_OFFSET_BITS=64 -O2 -g -pipe -march=i386 -mcpu=i686
    uname output: Linux beast.csl.sri.com 2.4.22-1.2188.nptlsmp #1 SMP Wed Apr 21 20:12:56 EDT 2004 i686 i686 i386 GNU/Linux
    Machine Type: i386-redhat-linux-gnu

    Bash Version: 2.05b
    Patch Level: 0
    Release Status: release

    On both machines my .inputrc contains :

    set meta-flag on
    set input-meta on
    set output-meta on
    set show-all-if-ambiguous on
    set visible-stats on
    Meta-p: history-search-backward
    Meta-n: history-search-forward

    On the machine running bash2.05a when I enter a partial line then
    press meta-p I get the bahavior I expect, it searches the history for
    the first matching line based on what has been type so far on the
    command line.

    bash# ca

    <meta-p pressed>

    bash# cat /tmp/foo

    On the second machine running bash2.05b when I enter a partial line
    then press meta-p bash ignores what has been typed so far, removes
    everything typed on the line and presents me with a colon.

    bash# ca

    <meta-p pressed>

    bash# :

    Why am I getting two different behaviors? Also the strangest thing is
    that if I copy the /bin/bash binary from the machine with the correct
    behavour onto the machine with the incorrect behavior it also does not
    behave correctly. What is going on?

    Thanks,

     - Mike Hogsett
