Description Stepan Kasal 2000-05-17 12:44:52 EDT
In construct like
%{?amacro:%{amacro -f}}
the %amacro inside gets %* macro pointing to an uninitialised memory,
ie. %* expands to a garbage.

Though it can be fixed by an assignment like *be='\0',
I decided to clean up whole grabArgs() function in rpm-3.0.4/lib/macro.c

Patch follows, I hope.

Comment 2 Jeff Johnson 2000-05-17 13:00:59 EDT
Can you include the defininition of the macro suse_update_config? Thanks.
Comment 3 Stepan Kasal 2000-05-18 03:17:59 EDT
The bug does not depend on macro definition.

%amacro(f) \
  echo %*


%amacro(f) \
   echo %{?*}

should be enough.

Then call

%{?amacro:%{amacro -f}}

The macro %* is always defined but in this situation (macro call isn't
terminated by \n, eg.) the %* replacement text point's to an uninitialised
memory.  This is why the bug is not deterministic.

Please read whole patch--it also deletes several unused variables.

Fixed in rpm-4.0-0.43 and rpm-3.0.5-0.4. Thanks for the patch, the cleanup
has been overdue for a long time now ...
