           Summary: Info documentation fails to install into directory
           Product: Fedora
           Version: 11
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: ocaml
        AssignedTo: gemi at bluewin.ch
        ReportedBy: matt at mattmccutchen.net
         QAContact: extras-qa at fedoraproject.org

    Classification: Fedora


Description of problem:

After installing the ocaml-docs package, ocaml is not listed in the info
directory when I run "info".  Here's the scriptlet that tries to install the
info documentation:

$ rpm -q --scripts ocaml-docs
postinstall scriptlet (using /bin/sh):
/sbin/install-info \
    --entry "* ocaml: (ocaml).   The Objective Caml compiler and programming
environment" \
    --section "Programming Languages" \
    /usr/share/info/ocaml.info \
    /usr/share/info/dir 2>/dev/null || :

Since /usr/share/info/ocaml.info is not an existing file (the file is
/usr/share/info/ocaml.info.gz), install-info misinterprets the --section option
as a "--section R SEC" style option.  install-info then crashes while
processing that option, due to a separate bug which I reported upstream:

https://savannah.gnu.org/bugs/index.php?27376

With that bug fixed, install-info would still fail with an error message that
is suppressed by the scriptlet.

Version-Release number of selected component (if applicable):
info-4.13a-2.fc11.i586
ocaml-docs-3.11.0-3.fc11.i586

How reproducible:
I got the crash every time I tried, but I'm hesitant to generalize because
behavior could depend on the layout produced by malloc at runtime.

Steps to Reproduce:
1. yum install ocaml-docs
2. info

Actual results:

The following crash during "yum install ocaml-docs":

And ocaml is nowhere to be seen in the info directory.

Expected results:
No crash, and ocaml appears in the info directory.
